In September 2015, Odjidja-Ofoe moved to Rotherham United on a one-month loan, making four appearances and scoring one goal against Cardiff City.

On 9 July 2017, Olympiacos officially announced the purchase of central midfielder Vadis Odjidja-Ofoe from Legia Warsaw, for an estimated amount of €2.5 million.

[7][8] On 16 August 2017, he scored his first goal with the club, as Olympiakos come from behind, in first half, to win 2–1 Rijeka in added time for the 1st leg of UEFA Champions League play-offs.

[9] On 22 November 2017 in an away 3–1 loss UEFA Champions League Group stage game against Sporting, Odjidja-Ofoe bagged the only goal of the Reds.

Odjidja-Ofoe came close to Sporting CP, but the change in the executive staff of the club and the immediate removal of Siniša Mihajlović broke down the Belgian player's transfer to the Portuguese team.

He made his second appearance for Belgium in an UEFA Euro 2012 qualifying game against Azerbaijan in March 2011, again coming on as a substitute in the 90th minute, this to replace Steven Defour.
