Sky Sports' Paul Merson predicts a 1-1 draw for tomorrow's clash
Merson said: "This is a massive game, but I just don't see how Liverpool win without Sadio Mane. I half-fancied them with Mane, but I can't see it now.
"It will be interesting to see how United approach it. You would like to think, with the squad and firepower they have got, that they will have a go. But we have said that before and they have parked the bus, so we will have to see what happens. It's a big game for Romelu Lukaku. Now he is with one of the big boys he has to perform against the big boys.
"Manchester United are a better team but Liverpool's home advantage should help them get a draw."
