Thomas Mavros (Greek: Θωμάς Μαύρος, born 31 May 1954) is a Greek former professional footballer who played as a striker.
Starting his career at Panionios, he quickly established himself in the Greek championship at the age of 16. He became one of the star players of AEK Athens and led the club to major successes during the 1970s and 1980s. Mavros is widely regarded as one of the best footballers in Greece, having scored a record 260 goals in the Greek championship and played for the Europe XI in 1981, as well as the World XI in 1984. He was nicknamed "The God" (Greek: Ο Θεός) or "Theomas" (Greek: "Θεωμάς").
In 2012 he also had a brief spell as president of AEK Athens.
Mavros was born on 31 May 1954 in Kallithea, where he lived for the first four years of his life, until his family moved to Palaio Faliro. His father, Michalis, despite not being a footballer himself, was a huge fan of football. From the age of five, his father used to take him and his brother to the yard of their house every morning, from 7 to 9, teaching them the basics of football. He also took them on Sundays to the Nea Smyrni Stadium to watch Panionios. His elder brother Sotiris, soon joined the children section of Panionios. For the seven-year-old Mavros, it all began on a winter Sunday in 1961, after his father refused to go to the stadium due to bad weather. Mavros decided to go alone to Nea Smyrni to watch a match of Panionios against Pierikos. He waited outside the locker rooms and caught the attention of the team's captain, Takis Papoulidis, who urged Mavros to go out with the rest of the team for the warm-up. At the suggestion of Papoulidis, the two of them played "headers", reaching 65 without dropping the ball. Papoulidis, recognizing the talent and abilities of the young Mavros, urged him to attend every match in the uniform of Panionios and to enter the pitch with the team as their mascot. In the first match in which Mavros served as a mascot, Panionios defeated Olympiacos by 1–0 and he earned 100 drachmas for the luck he brought to the team.
At the age of 11, Mavros joined the youth academy of the club and began his intensive involvement with football. The exclusion of his brother from the club's teenage section combined with the disappointment of his family brought him to train with the youth team of Olympiacos. There, Elias Yfantis identified his potential and asked him to join the team. Panionios refused to give him his sport's card, preventing the transfer and Mavros became disillusioned and temporarily withdrew from the club's activities. The situation was resolved by the curator of the club Papidas, after a visit to his house and a promise to 14-year-old Thomas for participation in the youth team. There, he worked under Dezső Bundzsák at the beginning and later Joe Mallett who recognized and developed his potential. On 8 September 1970 he was promoted to the senior team and he became the youngest player to have played in a Greek championship match, at the age of 16. He also the youngest scorer on 17 January 1971, when he scored the only goal at the 65th minute against Pierikos in a 1–0 victory. He also became an international at a very young age whilst not playing for any of the top clubs. On 16 September 1971, he made his European debut against Atlético Madrid in the first round of the UEFA Cup. His appearance made him the then youngest player of a Greek football club to have ever played in a European competition. Initially Mavros played as a left winger and later as a striker, where he showed his scoring abilities, attracting the interest from major Greek clubs.
In the summer of 1975, the president of AEK Athens, Loukas Barlos was interested in signing Mavros, but the board of Panionios rejected all offers, refusing to sell their best player. AEK were about to relive the adventures of the transfer of Kostas Nestoridis in 1955. The desire of Mavros to play for the AEK of the time, as well as his appreciation for Barlos were enough to overcome the efforts of the president of Panionios, Tsolakakis to block the transfer. It was later revealed that, when Mavros signed his contract with Panionios, he was still a minor, thus rendering the contract invalid. Panionios still blocked the transfer, which led to a legal dispute between the two sides that lasted for an entire season. During this period, he was unable to compete in an official match for either side and thus he was limited to playing in only friendly games with AEK. On 2 July 1976 the dispute was eventually settled out-of-court and Mavros was transferred to AEK Athens for the amount of 10 million drachmas.
The resolution of the case brought satisfaction to both Barlos and Mavros who developed a "father-son" relationship. From his first season, he became an integral part of the team, helping them reach the semi-finals of the UEFA Cup. With the arrival of Dušan Bajević he formed one of the club's most prolific attacking duos. The following season, he had a starring role in AEK winning the domestic double, emerging as the top scorer of the league with 22 goals. The team of Barlos did not stop there and won a second consecutive championship in 1979, while they missed the chance to win the domestic double, losing the Cup to Panionios in the final. Mavros was again the league's top scorer making a career record of 31 goals, while his performances of that season won him a Silver Shoe, finishing 3 goals behind Kees Kist of AZ.
The era after the departure of Barlos was marked with administrative and financial instability within the club, while the signings did not meet expectations, as the team became progressively weaker. In that period of decline for the club, Mavros stayed and with his leading presence helped maintain the team's competitiveness. He was particularly popular among the supporters of AEK, partly due to his loyalty to the club during a period of decline and his scoring performances in matches against Olympiacos. He earned the nickname "The God" (Greek: Ο Θεός), while the lexicographer Faidon Konstantoudakis also coined the nickname "Theomas" (Greek: "Θεωμάς") (paraphrase of his first name to resemble the Greek word for God) and whenever he scored the whole stadium chanted "Who, who, who? Mavros the God" (Greek: "Ποιος, ποιος, ποιος; Ο Μαύρος ο Θεός").
On 18 August 1981, Mavros was called to Europe XI to play against Czechoslovakia for the 80th anniversary of the Czechoslovak Football Association.
In 1982, he played a key role in eliminating Olympiacos in the quarter-finals of the Cup with 2 wins and his goal in the victory by 0–1 in the second leg at Karaiskakis Stadium. In the counterattack of AEK that led to the goal, Mavros got the ball at the center of the field and dribbled into the penalty area and many supporters of the red whites began leaving the stadium confident of the upcoming goal of Mavros and the consequent elimination of their team. In the final against PAOK at Olympic Stadium, his goal and another by Vangelis Vlachos led the club to win a title after 4 years. In the following season he renewed his contract with the club receiving 45 million drachmas from the then president, Lefteris Panagidis.
On 22 June 1984, Mavros was called to the World XI alongside his countryman Vasilis Hatzipanagis and other players such as Franz Beckenbauer, Ruud Krol, Johan Neeskens, Peter Shilton, Kevin Keegan, Mario Kempes, Hugo Sánchez and Felix Magath. Approximately 20,000 Greek spectators were present at Giants Stadium to watch World XI playing against New York Cosmos in a 3–1 win. In fact, according to Mavros, in the game, Beckenbauer told him "At last, you came.", referring to the constant interest of his team, New York Cosmos for Mavros.
On 27 January 1985, Mavros also became one of the nine Greek players in history to have scored 5 goals in a match against Egaleo where AEK won by 5–2. At the end of the season he finished as the league’s leading scorer for the third time in his career with 27 goals. In 1987, the manager of the club, Nikos Alefantos asked the president, Andreas Zafiropoulos not to renew the contract of Mavros, as he thought the player was "too old" to play for a club of that level. This was confirmed on 11 April 1987, in the home match against Apollon Kalamarias, when at the 80th minute Alefantos substituted Mavros, being booed by the fans. Zafiropoulos agreed to the request of the manager and Mavros was released from the club and returned to his former club, Panionios. During his spell at AEK he won 2 championships and 2 Cups, including the domestic double of 1978.
