Former Arsenal boss Arsene Wenger says Bayern Munich "stole" Serge Gnabry away from them.

Gnabry was again outstanding for Bayern in their Champions League win at Chelsea last night, scoring twice.

Wenger recalled: "He lacked a bit. I gave him to West Brom, it didn't work out at all. In fairness I think we had an agreement with him but Bayern stole him away from Werder Bremen.

"He's a good player, he needs good players of course, like everybody, but he has individual ability and collective ability.

"We had an agreement with him but because he didn't play at West Brom I let him go with the under-21s in the summer with the German national team.

"He did very well of course, he was fresh. We had prepared him for us to sign his new contract but then suddenly he wanted to go to Werder Bremen."

Bayern signed German international Gnabry for £7.2m from Werder Bremen in 2017, and Wenger said: "It was not Werder Bremen that bought him, it was Munich that bought him.

"Because six months later or less than one year later he moved from Bremen to Bayern, but it was a done deal before."

Asked if Arsenal could have prevented Gnabry from leaving for Werder Bremen, Wenger said: "No, because he was at the end of his contract and we thought that he would stay, because he told us he would stay."
