i guess our resident troll suggested that matuidi wasn't a key player for those squads which he won titles with.
those players that you mentioned are mostly unsung heroes, neither of them was a typical key figure whom the average fans appreciated, vidal being a rare exception. for example, who are the players you associate with liverpool's recent winning cycle? salah, allison, mané, van dijk, firmino or alexander arnold are praised every single time over wijnaldum, right? same goes for casemiro, who's rated below kross and modric every single time. i'm not talking about his importance, i'm talking about the perception of his importance. football fans usually want to see flashy players in their team, and workrate is often underrated (see mandzukic for juve).
anyway, i'd rather bash paratici for not signing better mids than matuidi himself. matuidi is not a tier 1 workhorse anymore, maybe he never was, but gives his all usually, and that's what he's capable of. this hysteria about his contract renewal is something i don't really understand. a team can't replace all its midfielders in a summer window, but that is exactly what tuz suggests.
and calma, rabiot will bench matuidi once his match fitness allows it.
