The issue with Chalobah is that he has a mistake in him every match. He was largely responsible for Chris Wood's goal against us in the first half of the season and made a couple of other clangers. He even made a mistake against Senegal leading to a goal.
Almost every center back will make a few mistakes in a season (LeCroix made at least 2 I can think of), but he seems to make a few more than the rest.
He somewhat makes up for it with his ability to head the ball, both defensively and on set plays.
Overall I agree with most people here. At most I think he's worth 20 million maybe with incentives pushing it to 25 (if he hits them it should mean he's worked his way into a starting position). If his wages are on 70k that seems reasonable.
Otherwise if they want 35 million for him, let him rot on the bench, or get loaned to Strausberg along with Mudryk, Chillwell, Sterling, etc.
