Maurizio Sarri has lashed out at Bayern Munich for their "unprofessional" behaviour after the Bundesliga club publicly expressed their interest in Chelsea starlet Callum Hudson-Odoi.
Chelsea boss Sarri is furious that Bayern sporting director Hasan Salihamidzic said this week that they "definitely" want to sign Hudson-Odoi during the January transfer window as he "has the qualities which would fit very well" with the German champions.
Chelsea have reportedly turned down a 35 million ($45 million) bid from Bayern for the 18-year-old, who has less than 18 months to run on his current contract and has so far refused to sign a new five-year deal, and Sarri is unhappy with Bayern's public approach.
"I think that it's not professional, because they are talking about a player under contract with Chelsea. So they didn't respect our club, I think," Sarri told reporters on Friday.
Sarri has handed Hudson-Odoi a place in his starting line-up for Chelsea's past two matches -- Tuesday's League Cup semi-final loss to Tottenham Hotspur and the 2-0 FA Cup win over Nottingham Forest last weekend in which the teenager set up both of Alvaro Morata's goals.
But, having helped England win the Under-17 World Cup, Hudson-Odoi could follow the same path taken by his international teammate Jadon Sancho, who has impressed for Borussia Dortmund since leaving Manchester City for Germany.
Regardless of Hudson-Odoi's future, Sarri has recommended Chelsea sign two new players to bolster his squad.
"As you know very well I am not involved in the market. I spoke with the club and the club knows very well my opinion. In my opinion we need two players," he said.
"Then it depends on the club decision. I don't know anything about the market day by day or minute by minute."
