Arsenal chairman Peter Hill-Wood admits their squad has looked short this season.
"We have always trusted Arsene's (Wenger) judgment," he said.
"Although our squad is not as big as Manchester United's, I accept we have lost a lot of key players this season.
"I am sure every club has its hard-luck stories, but it is seriously difficult to replace overnight world-class players like Fabregas, Walcott, Rosicky and Eduardo. Without them, we have looked a bit limited some of the time, and of course that has impacted on our Premier League results to an extent."
