Arsenal made it through by beaten Rennes 3-0.
Arsenal first leg switched
Arsenal and Chelsea were both drawn at home in the second leg of their ties but both teams are not allowed to play in London on the same or consecutive evenings.
So, the Gunners will now face the Italian side at home in the first leg because Chelsea won last season’s FA Cup.
The semi-finals will be played on 2 and 9 May, with the final on Wednesday, 29 May at the Olympic stadium in Baku, Azerbaijan.
