Matip has been very good this season playing alongside VvD, and he's actually managed to say healthy, but there's no way he should be our first choice CB pairing. In a more typical season where he's start-stop due to always picking up knocks, he's not very good IMO. I could also see him wanting guaranteed first-team football and again, I don't think he warrants it at Liverpool. He's worth keeping around but I'm not sure what his wages are, so if the options are sell him now for a fee or keep him for another year and let him go on a Bosman, I don't think it's terrible asset management to get another season out of him and let him go.
I'm a little surprised people aren't more interested in upgrading at CB. I like Gomez a lot but he's got major issues staying on the field. If you can sign De Ligt, you sign him and let let the chips fall where they may. Developing Gomez is a priority but between a massive fixtures list and inevitable injuries, he'll get playing time.
I absolutely want Brewster and Harry Wilson to get some looks but we could really do with a Julian Brandt type to spell our attackers. Another option up top for the front 3 and a first-XI CB and let's call it a day for the incomings.
