That game wasn't even a game that Man UTD would come out alive, it was suppose to be all about Liverpool with their outstanding form both in the EPL and Europa league, now we get to see a team that's not even close to their (Liverpool) standard to knock the Liverpool side out of the FA Cup, is really disappointing coming from Klopp and his boys.
This win doesn't show how good and promising the Manchester United team are because they have a way of messing up their performance in the next game, they can't be trusted even ETH knows his team can't stay consistent, so this win against Liverpool is not convincing enough to say they can win their next game.
If Liverpool can't get a win in that game (FA CUP) I think this is the time for them to start struggling in the EPL and the top 3 is going to be hotter than they can imagine unless Arsenal will start losing points for Liverpool to top them, but let's see what Klopp can do to amend his mistake.
That match really surprised me honestly, Manchester united players fought like wounded lions . I thought that match meant easy win for Liverpool, but with all their squad, they lost out of the competition. Somehow the results impressed me to see Liverpool lose their position for underestimating Manchester united. They started that match thinking that its a walkover, only after they conceded the first goal that they observed that Manchester united were very determined in that game.
Their determination paid off eventually and they sealed their place in the next round.
