Manchester United boss Sir Alex Ferguson believes Rafa Benitez's Liverpool team has already peaked - last season.
United host Liverpool tomorrow at Old Trafford.
Instead of building on their second-placed finish last term, Liverpool have crumbled, not even certain to claim a Champions League spot.
Not that Ferguson is entirely surprised.
"Sometimes you peak with a particular team and it is difficult to do it again," said Ferguson. "Everyone expected Liverpool to do better. But they are not.
"Their challenge, along with quite a few others, is to get that fourth spot, which seems to be a league of its own."
