Reporter Florian Plettenberg has claimed on Twitter that Kai Havertz may leave Chelsea at the end of the season.
The German is still struggling to impress on a regular basis after his big-money transfer to Stamford Bridge in 2020.
He has frequently been starting up front for the Blues this season, although he has only registered six goals.

His role in the side has up to now been relatively safe. Armando Broja has been ruled out for the rest of the season with a knee injury, and Pierre-Emerick Aubameyang has failed to impress since his summer transfer.
This month, the Blues have strengthened with the addition of Joao Felix on loan, likely to compete with the 23-year-old down the centre for the rest of the campaign.
Havertz could leave at end of the season
Reports have claimed that there is a clause in the Portugal international’s contract which could see him remain in West London beyond this summer.
This could mean trouble for Havertz, who will also need to deal with competition coming from Christopher Nkunku when the season ends.
Because of this, Plettenberg has claimed that he could be on the move if the Blues don’t finish in the top four this season.

He said: “News on Havertz: His future at Chelsea is uncertain! His departure in summer is possible.
“Decisive months could be May or June. Champions League next season is crucial for him. Price tag around €60m with possible bonus payments included.”
Top four is unlikely for the Blues this season, even if they turn their campaign around with the plethora of January additions.
The likes of Mykhailo Mudryk and Noni Madueke will certainly bring excitement on the wings, with the hope being that they can help bring goals to what have been a misfiring Chelsea attack led by Havertz this season.
