@Mantis Toboggan M.D. while they're not bad players in themselves, I think Liverpool could do better:
Yacob is nothing. Only thing he has is aggressiveness and thuggery.
Rondon - decent but I can't see him in the Liverpool side? Not with the style you play anyway.
Pieters - Always seen him as CB? Perhaps @Dickie could confirm. I may be wrong but even if he came in as cover, not up to Liverpool standard.
Sobhi - probably the only one that could improve under Klopp with how he plays
Cedric - with VVD, Lovren, Matip - another CB needed?
Romeu - now he would be better than Yacob! He would improve a lot of teams in the league.
Redmond - I think he's gone past the point of having potential. He's now 24 and not playing regularly for a side that's even going down? If you need a winger there's plenty out there that you could get that are better than Redmond (not Mahrez )
