Vulnerable at the back?
Having not been alerted to any new injuries in Graham Potter's Friday press conference it was a surprise to see Kalidou Koulibaly absent from the squad to face Manchester United entirely. There was a consideration that he may have simply being offered a proper rest, as Ben Chilwell received against Brentford but it soon became clear there was a problem.
"He just felt his knee at the back end of the game against Brentford," Potter revealed ahead of the game. "It's not too bad but it's too soon for him to play in this game."
