If Chilwell is out for any significant period, that's a huge blow for them. He's been in phenomenal form this season. Down as 3 goals and an assist in 6 (?) PL games. None too shabby for a full back. Has he really only played 6 times in the league so far?
Yep. Alonso was in the first team the first 5--6 games or so. Chilwell was apparently mentally exhausted and was held back by Tuchel until he was ready.
