Arsenal boss Arsene Wenger says midfield injury problems prevented him from making planned substitutions against Tottenham Hotspur.
The Frenchman was forced into substituting midfielders Mikel Arteta, Jack Wilshere and Aaron Ramsey on Saturday but insists the Gunners deserved to take all three points from the North London derby.
"It [injuries] did affect us but we had a go in the second half and were always dominating," the manager told Arsenal Player.
"It restricted the options to put strikers on.
"I only had one position left. [If] we could have brought Rosicky and Podolski on in the final 30 minutes, it would certainly have made a difference.
"I don't know [how long Jack will miss] because it's [the] ankle where he's already had an injury before. I hope [he won't be out] for a long time. Mikel and Aaron are out for [Galatasaray and Chelsea] for sure."
