Hopefully we'll have learned some lessons from the City game, because if not then there's the potential for them to do what City did in the first half: start with a high intensity attacking game we can't cope with, and grab a goal or two.
Luckily though they're shoddy in defence and if we play well we can expose them. Zlatan needs to ensure he's a constant hassle and putting them under pressure. Mata should play since he regularly pops up with important contributions, whether it be a goal or assist, in big games.
I've predicted a 2-1 Liverpool win, but the fact they're in good form and we've been a bit meddling makes me think we might surprise them and pick up a result. Klopp's Liverpool have often been inconsistent...although at the same they're also often very good in the big games.
