We've offered him £85K a week to stay. The club is desperate to keep him.
As for Sarri, it's a tough one, does he drop Eden Hazard for CHO? He's played him a fair bit out of position on the right. There's not many 17/18 years olds playing more than 18 games (that how many CHO has played in so far) for a Champions League chasing side. If we look at other top six sides and their 17/18 year olds:
Foden (older than CHO) is probably as highly rated but has played far less.
Chong and Gomes at Man United (both older than CHO) have played far less.
The season that Alexander-Arnold was the same age as CHO he played in 7 games (according to WIki). Rhain Brewster was in the same Under 17 England side that won the world cup. He's not played a minute for Liverpool.
Don't know of any teenagers currently breaking through at Spurs. Winks certainly was not playing that much at 17/18.
When Maitland-Niles was CHO's age he was on loan at Ipswich.
Chelsea have been terrible at getting youngsters through into the first team but CHO is being given more game time than any kid of the same age, despite sharing the same position as possibly the best player in the clubs history who is in his prime.
