Liverpool legend Dietmar Hamann has fired some words of warning towards his former club ahead of their visit to Old Trafford on Sunday.
Hamann, speaking to the Paddy Power blog, said that the Reds will struggle to handle Jose Mourinho's resurgent Manchester United, who he believes remain serious title contenders.
United made a poor start to the season but have rediscovered their winning mentality over the past couple of months, going 15 games unbeaten, and come into the clash off the back of nine consecutive victories.
'Once Mourinho’s teams start rolling they’re like a juggernaut, they can be incredibly hard to stop,' Hamann said.
