Is he though? I've seen very little of Tosin, but a lot more of Chalobah, and I'd not have him on a free. On top of that, Chelsea are supposedly getting rid, and getting inferior player in place? He's defender version of Tammy Abraham.
And what the hell is this flexibility bullshit, he's a CB. You want a RB, get a RB, not a flexible CB. Lindelof is fecking flexible too, we all know how popular that move is even before match has started.
So by all means, he'd be coming in as a CB, and at best, he'd be only ahead of Lindelof. 25 mil for 3rd/4th choice CB when we haven't got blank cheque and 50 more pressing issues is ridiculous.
