Callum Hudson-Odoi has already emerged as one of the biggest talking points in the January transfer window.
Despite having just 19 senior appearances for Chelsea, his remarkable talent has caught the eye of Bayern Munich and it's speculated he could be the latest young Englishman to move to Germany.
The Blues have rebuffed a number of offers throughout the month but it seems Bayern are closer than ever to securing a deal.
According to the Daily Mail, the European giants are now confident of securing a deal for Hudson-Odoi after agreeing a buy-back and sell-on clause with Chelsea.
That hasn't stopped Maurizio Sarri from expressing his discontent with Bayern, though, after the win over Newcastle United.
"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 remarked, according to the BBC.
"He is improving a lot I think in the defensive phase. Now, he needs to improve in some movements without the ball."
Sarri took the decision to bench Hudson-Odoi during the game, although introduced him for the nine minutes and it quickly sparked a reaction from Chelsea fans.
Journalist notices 'ominous' behaviour
Supporters have been keeping their fingers crossed that Hudson-Odoi will turn down Bayern and greeted their young star with a chant of: "Hudson-Odoi, we want you to stay."
A lovely gesture from the Stamford Bridge crowd but the 18-year-old's behaviour at full-time didn't exactly reciprocate the love shown from fans.
Journalist Liam Twomey - who works as a Chelsea correspondent - thought it was 'ominous' that Hudson-Odoi decided to stride straight down the tunnel in spite of the chants.
Considering it could have been his final game or a potential turning point, it was certainly some unexpected behaviour. Check out his tweet below:
An interesting decision, no question.
Coupled with suggestions from fans that the player simply didn't look excited when Sarri brought him on, there were some worrying signs from the winger.
It's hard to tell whether Hudson-Odoi simply wanted to avoid the cameras being on him or was in general disagreement with the chants asking him to stay.
There's great reason to suggest he would get more playing time in Germany, especially when you consider the recent successes of Jadon Sancho and Reiss Nelson.
It seems a decision will arrive in the coming days and Chelsea fans' chances of seeing him in west London for the remainder of the season are looking increasingly unlikely.
Like walking down the tunnel to positive chants, it looks like Hudson-Odoi could be striding out the exit despite calls for him to stay.
