That is true - How we haven't won some of the last few games i have no idea... haha!
Im looking forward to Ibra against Matip, think it could be a good battle.. But similarly to your thinking, I'm not quite sure how you'll be able to cope with our attack if it's anything like it has been
Liverpool's attack has been relatively good this season although not quite as good as hyped up to be. Shot maps show that the Coutinho effect was in full flow against Burnley. Liverpool's attack was really good against Leicester and Hull. Yesterday's game against Hull was one of the best at taking performances in the league so far.
Defence doesn't convince me but hasn't been as bad as made out to be. Metrics show that 4 goals for and against Liverpool wouldn't have been scored at league average profligacy. Burnley was also a freak game in terms of goals conceded. Having a better keeper will help. There are also half a dozen teams better at the back though.
Liverpool are one of the hardest teams to play through in the league tactically. There are stats backing this up. I think Klopp has been trying to get the personnel to fit his counterpress. Sevilla adjusted to it in the Europa final and won it. Same with many games last season. It is a reason why Liverpool are hard to play against. I think more so than attack. Liverpool's attack under Klopp thus far but chance quality has been pretty meh (**** Coutinho) and it can look as if Liverpool attack better than they actually do. Thomas Tuchel's Dortmund side are far better chance creators than under Klopp. If Liverpool shoot from better positions or blitz it like at Hull, it would give United something to think about.
