Our fullbacks are fine. Robertson has been excellent and Moreno is fine as a back up if we take into account his form at the start of the season. Clyne is back and is always reliable and Trent-AA is taking leaps and bounds foward. Even Gomez while covering Clyne has look great bar a couple of lapses in concentration.
Basically we definitely need a new #6. I'd much rather a deep lying playmaker #6 like a Xabi Alonso mould than a "true CDM" and as
@OneFootball said I'm pretty sure Klopp has made that clear previously that he's not interested in signing a CDM. Jorginho certainly matches the criteria for that role which is why I was so excited when we got linked to him. Another player I quite like for that role is Rabiot who coincidentally is a Liverpool fan.
Beyond the #6 role I think there's 3 other positions we should be considering:
- New #10 which again as OneFootball said they'd need to be able to link the attack but also offer a bit more in terms of defensive work rate than Coutinho did. Fekir would be the ideal pick for me. He's got a similar defensive work rate as Firmino (in terms of tackles and interceptions), he's excellent on the ball and provides a lot of chances for others. He also can cover both wings and play as a false 9 which is a huge appeal for me as well as it gives us an easy solution to resting Firmino, Mane and Salah.
- New RCB. I feel like Matip and Lovren are on trial for that RCB position right now and if neither show they're of the quality we need then I'd sell the worst and bring in a new CB. Obviously I'd love Alderweireld but that won't be easy.
- New GK. Similar thing for Karius, he's basically on trial at the moment. Mignolet will go in the summer so we'll sign a keeper regardless I'm sure. But whether we get a new number 1 or number 2 is purely based on Karius' performances until the end of the season. We're being really strongly linked with Alisson and he looks absolutely class so I'm all for it regardless of how Karius plays.
3-4 high quality signings in those positions above and I personally believe we'll have our best PL squad ever, better than 08/09. Lets hope that Coutinho money + summer sales gets used well!
