The priority's for the money/ real quality signings should start with a 'keeper and dominant midfielder. Either BTB or DM dependent on where Grujic is slated to play. Maybe a LB dependent on whether he thinks Flanno is good enough to start. Everything else at FB is set with Clyne among the leagues best on the right, and Smith making the major leap to show he's first team squad ready. Centre half is interesting. You could argue for another top bracket one alongside Matip. (Who also gives depth in the DM role.). But then how will Lucas develop there? And let's not forget the immense promise of Joe Gomez. Can't see Lovren going anywhere and he's improved to at least be reliable depth. I'd off load Sakho if he has a decent Euro's whilst the price is still high. Don't get the cult status with him at all. And I've already discounted Skrtel and Toure being here for next year. A quality DM who is also rangy is sorely needed as mentioned. But you throw in, hypothetically, say Gotze as a name, along with Grujic and A N Other, and the two Brazilians quite possibly then step up to the ability we know they have with better quality around them. Could do with another out and out striker, but Sturridge, Ings and the developing Origi, who's come on leaps and bounds under Klopp from the player who never looked like he'd make a footballer under Rodgers is a good mix.
I love the fact we have two signed, Matip and Grujic, with the returning Markovic hopefully like a completely new £20 million signing to give added attacking options. That's three right there. Add a quality 'keeper, commanding central midfielder, and A N Other along the lines of a Gotze and that's improved the first XI immeasurably. Then we'll see on out goings what depth we need to add. A situation where the likes of Lallana and Milner are solid back-ups would be a major step forward in personnel.
I also like that Klopp's savvy and won't over pay just because. If the quality's there he would, but he's far more about the right players that fit rather than just a name.
