"We've got to try and get a fit team out for Wednesday night. We've got Arsenal and that's a massive game," he said.
"In my opinion I couldn't have asked for a better game. If I could choose a game it would be Arsenal at home.
"This wasn't ideal preparation that's for sure, but the players will have a rest now and we'll get ready to go again.
"With Manchester City winning this has been one of those days. This is a big blow and the mark is how you pick yourself up from these types of days."
Niko Kranjcar sustained an ankle injury and is a major doubt for Wednesday while Wilson Palacios will miss his next two games after picking up his 10th booking of the season.
Ledley King (thigh) and Aaron Lennon (groin) are doubtful to face the Gunners.
