RB Leipzig forward, Christopher Nkunku, has signed a pre-contract to join Chelsea next summer, The Athletic reports.

Nkunku signed a two-year extension with the German club earlier this year, taking him to 2026.

However, his new contract contains a €60m (£52.4m) release clause which kicks in next summer.

It is, however, believed Chelsea are prepared to offer more than the release clause in advance of the summer to ensure they get Nkunku ahead of other interested clubs.

Nkunku joined Leipzig from Paris Saint-Germain in 2019.

He has scored six goals in eight Bundesliga appearances this season and has made eight appearances for his country.
