Roma win proof of Arsenal's mental strength, says Wenger

ROME: Arsenal's mental strength has been called into question recently but coach Arsene Wenger said it was a key factor in his young side's penalty shootout victory over Roma in the Champions League on Wednesday.

Arsenal prevailed 7-6 in the shootout after Roma's Brazilian defender Juan's early goal had cancelled out the Londoners' 1-0 advantage from the first leg.

"After missing the cross to concede the goal and missing the first penalty, we needed something special to come back and win," Wenger told a news conference.
