Hudson-Odoi has only made one substitute appearance in the Premier League this season but has starred in cup competitions for the Blues.
Speaking ahead of Saturday's Premier League match with Newcastle, Sarri added: "As you know very well I am not involved in the market".
That fee would indicate Bayern see Hudson-Odoi as a player who can contribute right away and Robben, who will be departing the German club at the end of the season, thinks that when an opportunity to comes along, it behooves a player of the youngster's talent to take it. 'I don't know why someone would go to Bayern Munich'.
'That is all he needs to do, he has all the conditions to be a great player, now it is up to him to fight for a place here or try to find more minutes somewhere else.
"He is really very important for us and it is impossible to lose him in January".
"I am very happy with the player and would like to have him in the future".
After Eden Hazard was deployed as a "false nine" in Tuesday's Carabao Cup semi-final first leg loss to Tottenham, it appears Olivier Giroud is likely to start up front against the Magpies.
"It's normal", Sarri said. We need to improve in attacking the spaces.
