I'm not that fussed about losing the player - he is very up and down - but I would have thought we would need to bolster the cover at the back. Otherwise, we are very exposed to Lovren getting injured (and he's picked up a few injuries while he has been here) as we don't know if Matip will live up to his billing and cope with the physicality of English football.
Given his main LB target appears to have been a teenager with only 8 Championship appearances under his belt, it shouldn't be surprising that he rates Moreno higher than most commentators do.
If we are going to play a midfield three then you have to assume it will be Can, Henderson and Wijnaldum as first picks. We then have Gruijic, Lucas and Lallana in reserve. (Personally I'm not sure about Lallana in a midfield three but judging by today's line-up Klopp obviously thinks otherwise.) Perhaps the midfield three was a function of Can not being available and we will revert to a midfield two when he is available. Time will tell.
Thought he got through a lot of work today as the deepest of the midfield three. He didn't always get that much help from Lallana and Wijnaldum either. Battling display all in all.
