Arsenal captain Cesc Fabregas says Theo Walcott was the game changer in their 2-2 draw with Barcelona.

Cesc stroked home the equalising penalty just before the end but it was introduction of the Englishman in the 66th minute that sparked the revival. He scored three minutes later and helped his side finally put Barcelona on the back foot.

"Theo made such a difference," Fabregas told arsenal.com. "He went behind them. He created a lot of problems and I think he was the best player.

"We were dead at 2-0. You could never imagine we could come back. In the first half we never saw the ball. You thought you were going to get the ball then they changed sides. In the second half they scored two great goals but we had great spirit and comeback. Not everyone does that against a side like them.

"Overall it was an amazing experience and an amazing game. I will remember it for the rest of my life. My injury makes it bad but I think I would have done it anyway without being injured before."
