Premier League big spenders Chelsea have triggered Michael Olise's release clause at Crystal Palace.
The winger, who was a part of the Blues' academy at one time, is heading back to Stamford Bridge.
Per The Athletic, Chelsea are close to sealing a deal for the France Under-21 star.
Olise had an excellent season last term, which earned him interest from Chelsea and Manchester City.
However, he has chosen Chelsea and marks a huge spending couple of weeks for the Stamford Bridge team.
Chelsea have now spent 906.8 million on transfer fees since the club was taken over by co-owner Todd Boehly.
