Bayern Munich sporting director Hasan Salihamidzic has angered Chelsea by talking publicly about the club’s desire to sign Callum Hudson-Odoi yet again.

Chelsea are desperately trying to convince Hudson-Odoi to stay at Stamford Bridge and sign a new five-year contract amid strong interest from the Bundesliga club.

Bayern have had four bids rejected so far, the last of which was worth around £35m, but they are refusing to take no for an answer.

Salihamidžić has already upset Chelsea and their coach Maurizio Sarri by talking openly about Hudson-Odoi last week, but that hasn’t stopped him from doing it again.

Speaking in German publication Sport Bild today, he said: “We want to sign the player. I have no doubts about his abilities. We are in constant contact with Chelsea.”

The west London club have taken a dim view of Salihamidžić’s latest comments and see it is another attempt to unsettle their player.

Chelsea already suspect Bayern of making an illegal approach for the 18-year-old winger, who joined their academy in 2007, because they have kept making offers for him despite being turned down.

However, they have stopped short of making an official complaint to Fifa so far as it is a hard thing to prove.

But Sarri made it clear last week that Chelsea were not happy with Salihamidžić saying things about Hudson-Odoi to the German media.

He said: “I think it’s not professional, because they are talking about a player under contract with Chelsea. So they didn’t respect our club.”

Hudson-Odoi was first offered a five-year deal last summer but refused to sign it because he wanted to see how much game-time Sarri would provide.

The Chelsea coach has played the England Under-21 international just eight times, although he has significantly featured in the last three matches, including a start in the first leg of the EFL Cup semi-final against Spurs.

Hudson-Odoi has just 18 months left on his current deal and Bayern are warning Chelsea that their offer will be much lower than their last one of £35m if they wait to sell until the summer.

However, Chelsea hope that by playing him regularly from now until May, Hudson-Odoi will be persuaded to stay.

Chelsea fans were given some optimism that the teenager is having a change of heart when he posted on Instagram yesterday: “Don’t always believe what you hear.” It has since been deleted.
