"Last season we didn't have the resources to get through to the second leg of the semi-final against Milan in Italy," he said in the Manchester Evening News.
"If we'd had better resources we'd have got through. But we have a stronger squad and a more complete squad this season. The secret is keeping them all fit.
"Today I am lucky I have 22 players here and only Gary and Silvestre not here. It is a fantastic position to be in at this time of the season. If we can keep that it will definitely without question give us a chance.
"The midfield area is where I have the best options. On Saturday we brought a couple of fresh players in, in Fletcher and Carrick, and they were outstanding.
"You could say I have selection headaches. But when you are picking a team at the level we are at I don't think you look upon that as a hindrance to achieving the result."
