Wenger's men lost 2-1 to Galatasaray on Sunday - former Chelsea striker Didier Drogba scoring both goals as the Turkish outfit came from behind to win the match and the tournament - after a 2-2 draw with Napoli a day earlier.

Liverpool forward Luis Suarez remains Arsenal's primary target, as the Anfield club insist their Uruguayan front man is not for sale.
"If the club can target players that are going to improve the team, they are going to be very welcome because that's what we want - to get a better team, better players and compete to win trophies," midfielder Mikel Arteta told BBC Sport.
"But the club is working on that, it is in their hands and I'm sure they are going to do it."
