Maybe my expectations were excessive but I thought the plan for Pavard was for him to be something akin to the right-sided version of Bastoni, a balanced player who could push forward and add another creative element to the build-up. We know Inzaghi is happy for his central defenders to do this. In reality we have seen little of this, even when he has played with Darmian at wing-back who himself is more defensively orientated. Bisseck looks much more of an attacking threat, carries the ball forward better, is an aerial threat in the opposition box and can even improvise to score weird goals like the 5th against Verona.
Their respective stats thus far:
Pavard - 3,493 mins - 0 goals - 4 assists
Bisseck - 1,950 mins - 3 goals - 3 assists
So Bisseck has offered more in a little over half of the playing time. The other role is the defensive side of course and while Bisseck has undoubtedly had some defensive lapses, he has put in some great performances too, especially in big games like the Man City one. Can anyone say they are especially convinced defensively by Pavard? He had moments last season undoubtedly, but he is as others mentioned susceptible to anyone running at him, anyone with a burst of pace over the first five yards he has gotten too close to and he is very, very poor when required to compete for defensive headers.
I'm not saying that Pavard has been a bad signing, but when judging these things all assessments have to be relative to cost. Pavard cost 4+ times as much as Bisseck and earns 4+ times in wages, even after Bisseck's new contract. I think Bisseck has been an excellent signing and all criticism of him has to be put through the filter of him costing us next to nothing. Criticism of Pavard has to be put through the filter of him being a senior-international with vast experience of elite club and Champions League football that we thought would be a game-changer.
