Playing higher up and with possession will make a massive difference to all our defenders. I wouldnt write off a renaissance from any of them (bar Rodon, who has always been crap)
The problem with your logic is Dier is neither good in possession nor is he quick. Romero isn’t rapid either but he is good on the ball and VDV looks like he has pace if nothing else.
