Chelsea have made an enquiry to sign Bayern Munich winger Mathys Tel amid interest from the German side in their forward Christopher Nkunku.
The Blues, who first expressed an interest in Tel in the summer, have told Bayern they are willing to make an offer for the 19-year-old should he become available.
However, they have not offered Nkunku in a swap deal despite knowing that Bayern have had a longstanding interest in the 27-year-old France international, who joined Chelsea from German club RB Leipzig for £50m in 2023.
It isn't known how likely Chelsea's approach is to succeed given Tel is under contract until 2029 at the Allianz Arena – or whether the winger would try to force through a move to Stamford Bridge.
