Speaking to the media, Pochettino said on Thursday: "We still need to assess a few players like Chilwell after playing two games. I think he got a knock in his knee. Today, he wasn't ready to train. We will see what will happen tomorrow if he can be in the squad.
"Chilwell's injury a surprise? Surprised, not surprised, I don't know. If he cannot play with us or be available, because he didn't play after Brentford with us. He played a few minutes against Leicester. He started two games. Yeah, maybe, it's a surprise for us. But it's bad luck because he got a dead leg in the last moment of the game against Belgium."
