The transfer of Andreas Doi to Rio Ave from Olympiacos has been finalized. The Greek international center-back has been loaned by the 'red-whites' until the end of the season. As Doi was not recently included in the squad, it was considered appropriate for him to gain playing time elsewhere. This season, he has participated in 6 league matches for Olympiacos. Doi's move to Rio Ave increases the number of Olympiacos players at the Portuguese club, with Angelo Sina, Kostas Kostoulas, and Nelson Abi also on loan, and Marios Vrousai having been transferred permanently.
