Keita could have been one of many that got taken off last night, so I do not think it is the end of him.
We needed to get our foot on the ball in MF, that is not Keita's game even when he is playing well, he runs with the ball and opens defences, the danger is he often loses the ball, I don't know why Klopp didn't play Thiago, seemed the perfect game for him, he holds the ball, can pass and knows RM very well.
Usually I would say 3-1 is not a terrible result, the away goal is important and at Anfield we are capable of turning that around, but at an empty Anfield with no crowd pushing us on, with our current form, I think RM will just sit back and keep the ball, playing those long balls over our CB's.
Maybe we should take a leaf out of RM book and get them over to Kirkby to play, I am sure a few locals could make allot of noise outside the training ground !!!!
