Arsenal manager Arsene Wenger says Kieran Gibbs gave balance to the squad after coming on as a substitute against Tottenham Hotspur.
The Englishman was Arsenal's hero after restoring parity in the second half and the Frenchman was full of praise for the 26-year-old.
"He [Kieran Gibbs] played there when he was a kid," Wenger said.
"Always when he comes on, he balances our team. I had very limited offensive options on the bench. It gave me as well an opportunity to put Alexis on the other side where he could give me a different option. Overall it worked, but he gets in good positions and shows he is an intelligent player.
"[Mathieu] Debuchy finished tired because he played against Bayern, and played today, and had not much competition, but he looks alright."
Asked about striker Olivier Giroud's missed chances, Wenger added:
"[Olivier] Giroud is very angry," he said.
"I'm pleased [that he is]. When you see players happy to miss chances you can worry. He is a real goalscorer, he did try.
"In the last two games, against Bayern and today he worked extremely hard and maybe he wanted too much to score in the end, and especially the opportunity he had in the six-yard box, but that can happen."
