Tomić started his career playing for Radnički as a teenager, and made a name as a good young player.

New chairman Kokkalis appointed Giannis Ioannidis as head coach, with a goal to put the team in European basketball's elite.

The coach wasn't so impressed with Tomic's basketball skills or physical attributes, but liked the young boy's passion, cleverness, and will to win.

Olympiacos also returned to European competitions, and reached the EuroLeague quarterfinals, with Tomić averaging 32.5 minutes and 8.3 points per game.

They lost both EuroLeague Finals, but the fact that they won against Panathinaikos in both semifinals was a big consolation for their fans.

A few months later, Olympiacos participated in the 1997 McDonald's Championship, and made it to the final, where they faced the reigning NBA champions, the Chicago Bulls.

Soumpotits brought along with him to the team, a young talented point guard named Theo Papaloukas.

Papaloukas' presence reduced Tomić's playing time, but on the other hand, their rotation, and sometimes combination in the lineup, made the team better in matters of team-play, organization, passing, and defense.

Later that season, Olympiacos faced Panathinaikos in the Greek League semifinals, having the home court disadvantage, and still managed to "sweep" them in two games.

Chairman Kokkalis decided to fire head coach Dragan Šakota, and to everyone's surprise, asked Tomić to take the empty spot on the bench.

Under his reign as head coach, the team improved and played better, but was eliminated in the Greek League playoffs.

The season ended, and Tomic asked for a multi-year contract, so he would have the time to build a new winning team.

The team's new directors didn't like his demands, and gave his head coaching position to Milan Minić.

It was a big embarrassment for the Olympiacos fans, who were furious, and began swearing at players, coaches, and team directors.

In January 2005, Lefteris Soumpotits took over as the head coach of the Italian club Sicc Cucine Jesi, and he brought Tomić, who was a free agent at the time, along with him, to help save the team from relegation.

Tomić made yet another effort to continue his playing career, and signed a contract with the Greek club Kolossos Rodou, in January 2006.

[6] On 13 July 2018 Tomić was named a head coach from his hometown Belgrade-based team Crvena zvezda.

In December 2021, Tomić took over the head coaching job for Peristeri of the Greek Basket League, replacing Sotiris Manolopoulos.

[11] His son, Alexandros Tomits Liafou (born 2002), is a basketball player for the Crvena zvezda U16 team.
