Real Madrid have agreed a deal to sign forward Eden Hazard from Chelsea for a fee that could exceed £150m, BBC reported.
Hazard has agreed a five-year contract and will be presented as a Real player on 13 June, subject to a medical.
The Belgian scored 110 goals in 352 games for Chelsea after joining from Lille in 2012, and scored twice as they won the Europa League final last week.
"Leaving Chelsea is the biggest and toughest decision in my career to date," said Hazard.
Writing on Facebook, he added: "I hope you understand I had to pursue my next chapter, just as each and every one of you should when you have the chance to pursue your dreams.
"Now it's in the open I would like to put on record one thing was always clear to me, I have loved every moment at Chelsea and not once did I ever consider, nor would I have left for any other club."
