his presidency, Marinakis appointed fans' favourite Ernesto Valverde as coach (who came back for a second tenure in the club) and signed players with international pedigree, such as Albert Riera, Ariel Ibagaza, Kevin Mirallas, Marko Pantelić and François Modesto. As a result, Olympiacos won the Greek title for the 38th time in its history, 13 points ahead of second-placed Panathinaikos. In the 2011–12 season, the team's roster was strengthened with players like Jean Makoun, Pablo Orbaiz, Iván Marcano, Rafik Djebbour and Djamel Abdoun and with Ernesto Valverde as their coach for the second straight season, Olympiacos had a very successful campaign both domestically and internationally. They won both the Greek league and the Greek Cup to complete the 15th domestic double in the club's history.

They won the first match in Ukraine with David Fuster scoring the winning goal (0–1) but in the second match, despite their early lead and the plethora of missed chances (they hit the woodwork twice in the first half), they conceded two goals in the last nine minutes of the game and lost the qualification to the quarter-finals.

Despite the relatively good results, Leonardo Jardim was
