What stopped them putting a serious challenge to us last season?
Squad depth, losing games against teams in the lower half of the league that they shouldn't and Individual errors, mainly in defence and goalkeeper.
The addition of Van Dijk in January helped the defence, and the recent arrivals of Fabinho, Naby Keita, Xherdan Shaqiri and Alisson will add depth and improved quality, Alisson definately improves the goalkeeping.
They will be improved, but other than Shaqiri, the others will take some time to get used to the Premier league. There will also be an element of getting the blend right, players like Henderson and Milner are going to have to get used to spending time on the bench, and they have lost Can.
They will be closer to us, and likely to be our biggest challengers, but nothing we can't deal with.
Bring it on.... now I wonder if I can get odds on Klopp been gone by this time next year.
