Makes sense to sign him but probably we could get rid of Wan Bissaka, right? I'd assume we could get decent money for him.
Dalot is still young so might stay. We get Pavard to cover for RB for one season, next season we get a proper attacking full back and Pavard goes for CB. That makes sense as a transition move. Otherwise I'd rather just go for younger/faster CBs mentioned earlier (before our interest in Pavard has been revealed). We have enough cover for RB. I can't imagine both Wan Bissaka and Dalot sitting on a bench.
Wan Bissaka is a very good stand in or specialist we can roll out for key games or elite players in key duel games. He's a very useful squaddie to have this season. Dalot covers both LB and RB, which also gives him purpose particularly in indirect cover for Lisandro (Shaw going to CB) as Malacia then doesn't necessarily have to see the pitch.
I understand the clamour for a much better CB, but Pavard raises our right flank prospects so massively this season that he - or what is on offer - shouldn't be casually overlooked. Any CB that comes in starts on the bench and is reliant on Varane needing rotation or being injured to get games - they don't strengthen the 1st xi out the gate. Pavard does, and that's worth something in and of itself.
If the club opt for the elite CB prospect understudy this term, our RB's or even right flank, remains a massive weakness in the team, so it's a horses for courses/ pick your poison scenario on what, ultimately, you'd think is best for us. There's also the short, mid and long term gains/losses of the direction taken with the CB being a great mid and long term benefit and Pavard being the short and mid-term no-brainer given he himself would be upgraded upon further down the line, most likely.
