Chelsea are starting to dominate the talk of the January transfer window, with the club involved in a number of developing stories.
Over the last few days, news has broken about Barcelona's interest in a couple of players - Willian and Alvaro Morata.
Reports suggest that the Spanish club offered a cash plus Malcom deal for Chelsea's Brazilian winger - which much to the disappointment of fans, was turned down by the Blues.
On top of that, Sport have been claiming that Barca are interested in taking Morata on-loan, which is also baffling Chelsea fans.
But, they're not the only club that's been sniffing around players from the west London club this month.
Fellow European giants Bayern Munich have made their interest in Callum Hudson-Odoi clear.
The German side have made a number of bids for the 18-year-old, with the latest reportedly matching Chelsea's £35 million valuation of him.
NOT KEEN TO SELL
However, it's understood that the club are desperate for the teenager to stay, and that's far from surprising considering the talent he already has.
Despite all this, Bayern have been very public about their interest in Hudson-Odoi, so much so that Chelsea could report them for 'tapping him up'.
Clearly, things have turned a bit sour between the two clubs, and in his press conference on Friday afternoon, Blues boss Maurizio Sarri made it very clear how he feels about Bayern's pursuit.
"I think that it’s not professional, because they are talking about a player under contract with Chelsea," Sarri said, per the Guardian.
"So they didn’t respect our club, I think."
It's certainly quite rare to see a top manager directly address and even hit-out at another club's attempt to sign one of his players.
Clearly, Bayern's interest in Hudson-Odoi has rattled Chelsea, and it looks like they're doing as much as possible to keep him at this stage.
