Hard to say really, Craig, but for me he would have given us the composure in midfield and the ability to spread the play. There were times when the ball needed to be switched and no one took that option. Arteta played one raking ball, yes, but other than that he always dribbled sideways across the pitch.
For me, Fellaini would have played those long balls to the flanks like he has done in recent matches. That would have stretched the play and made Liverpool work harder to win the ball. We didn't do that enough in the second half, amongst other things.
