He made seven appearances in his debut season, scoring one goal, as Hibernians recorded a sixth-place finish in the Maltese Premier League.

The 2000–01 season saw Cohen firmly establish himself in the Hibernians first team squad, as he helped to a fourth-place finish in the Maltese Premier League, making 19 appearances and scoring three goals.

Cohen's good form did not go unnoticed as he received his first cap for the Maltese national team, starting in the 3–2 defeat to the Faroe Islands on 18 August 2004.

For the 2008–09 season, under the guidance of new manager Mark Miller, the club shocked the critics and beat Valletta by two points to win the Maltese Premier League title.

On 9 November 2024, he resigned as Manager of the Club because they failed to qualify for the top 6 by goal difference when they lost against Ħamrun Spartans 2 days early.
