"They are one of the best teams in the world," said the Rovers chief. "We are all aware of the task ahead of us, but it is a task that we are relishing and really looking forward to.
"They've got a fantastic squad - not just the eleven players that they put on the pitch. Anderson will probably come in or (Darren) Fletcher or (Ryan) Giggs, so we are still talking about world class players replacing world class players. Then you've got (Dimitar) Berbatov and (Carlos) Tevez as well.
"They are such a good side it doesn't matter who they field against us, it is going to be a very, very tough game.
"But that is the exciting aspect of coming to the Premier League and managing. You get the chance to pit your wits against the best manager of all time as far as I'm concerned. It will be nice to lock horns."
