Arsenal legend Ian Wright says Mikel Arteta's side still have more they need to learn following their Champions League elimination.
The Gunners surrendered the top spot in the Premier League after a 2-0 defeat to Aston Villa meant Manchester City remained above them in the table, despite having plenty of chances to score.
Then on Wednesday, Joshua Kimmich scored a second-half header to send Bayern Munich through to the Champions League semi-finals at the Gunners' expense.
Wright believes fatigue may be an issue, highlighting Ben White's part in the Bayern winner on Wednesday night as an example.
