The only thing I can say is that JK is planning on playing a different style than the one I'd naturally prefer. I will hope he's got it all planned out and that it works the way it should. I'll just have to wait and see, and it may take a while because I never expected that he'd be able to do it all in one transfer window; it actually could be next summer before we see a more true and complete Klopp side.
I was never the biggest fan of Joe Allen, but looking back and thinking about it, he always seemed to get unlucky with picking up an injury at the wrong time. Last season was much better And he looked to enjoy playing for JK, so I'm surprised he's not been offered a contract and the bargain price that's being accepted makes it look like the club is happy to let him leave.
I actually like players like Allen, Lucas and even Can ( and Milner too ), midfielders who are not all flash and bang but actually just put in a lot of hard work denying the opposition, winning the ball back and, of course most importantly, keeping it. That's why I get slightly concerned and envious when I see the likes of Utd, Chelsea and Arsenal signing players like Pogba, Kante and Xhaka and we are letting our midfield workhorses leave the club.
The new additions are all decent players: Grujic is still very young and first time away from home, he could be anything and nothing; Mane and Wijnaldum are both good players and proven to handle the PL. None of them are 'protect the CB's ' type of midfielders though, and our central defence could do with some protection. Wijnaldum in particular is not known for putting his foot in and he tends to play on the left of midfield, you know, the same side as Moreno! A team with Moreno, Wijnaldum and Coutinho on the left would be a little concerning for me ( although, undoubtedly, they'd create a huge amount of chances going forward )
We'll just have to wait and see what happens, still five weeks of the transfer window to go and plenty of time for that upgrade at left back.
