The French side are looking to finally end their long wait for a European title, having not won a major continental trophy since the 1996 Cup Winners’ Cup.
Serie A side Atalanta have only reached a European semi-final once, also in the Cup Winnners’ Cup and way back in 1988.
Both teams face injuries and absences, but will still feel they have a real chance at going all the way thanks to their attacking consistency.
