Bayern sporting director Hasan Salihamidzic admitted the club's interest in Hudson-Odoi on Wednesday, much to Chelsea's annoyance, with the Blues threatening to report the Germans to Federation Internationale de Football Association if there is any evidence of an illegal approach.
Chelsea, however, have not given up hope of changing Hudson-Odoi's mind, and Sarri - who picked the 18-year-old to start against Tottenham in the Carabao Cup semifinal first leg at Wembley on Tuesday - hit out at Bayern. "I spoke with the club and the club knows very well my opinion", he said.
And if we consider, Bayern's reluctance in handing over opportunities to young, inexperienced players, a move for Callum-Hudson is certainly an unconventional one, especially for a reported fee of £35 million, which would make him the third most expensive arrival in the club's history.
Robben netted 19 times in 105 games during three seasons at Chelsea FC before the Dutch winger moved to Real Madrid having won two Premier League titles under Jose Mourinho. "Of course, for playing as a central midfielder in our team is not easy", said Sarri.
"And I've told him the Bundesliga is a nice league".
"Every young player in England wants to do well and just wants to help their families, be someone that their family can be remembered for. I think that he is able to do it".
"The player who plays in that position usually touches the ball about 120-130 times and so I think that we need a specialist there".
"I've told them [his former England youth team-mates] that this is a league that is keen to express the youth", he added.
"He's the next one I would say". It depends on the club decision.
Do you think clubs should punished for tapping up players? "I don't know anything about the market day by day or minute by minute".
"I think that is not professional because they are talking about a player under contract with Chelsea", Sarri said. We need to improve in attacking the spaces.
"We need to try and try and try in training with him".
Sarri did, however, admit that he has given up telling Hazard to focus on "the final 20 metres of the pitch" when he plays as a false nine.
