mate ake is still very much a backup. and we need a backup right now, because dias is injured and walker's injured.
and that's actually the perfect example for why we need to get a 30m player and not a 70m player. imagine if in ake's position right now we had a 70m player, with how little minutes he's gotten this season? you'd have a word of trouble keeping them happy. You need someone to fill in in these exact scenarios.
Right now we don't have defensive problems even with the tiredness and injuries because we invested in that ~30m backup, we need to do the same for the CDM position.
