Willian has suggested that he intends to remain at Chelsea for the upcoming campaign. Gunners boss Unai Emery is keen to keep Ramsey, whose current contract expires next summer, but no new deal has yet been agreed.
"Since the beginning, he told me he loved Chelsea", he said.
Courtois' future has been the subject of speculation for much of the summer after he said he wants to move to be closer to his family who live in the Spanish capital.
"Chelsea are quoting Madrid £225m for Hazard", said Keys, adding that "Courtois insists he wants to go as well".More news: 5 killed in CA when plane crashes into parking lot

"Without doubt, we all like this style of play, all the players", he said. "Everybody loves them and I hope they can stay". "I think he will be a very useful player for us".
As Chelsea were being outclassed by Manchester City in the Community Shield at Wembley on Sunday, want-away goalkeeper Thibaut Courtois was honoured by one of his former employers.
A disappointing fifth-place position under Conte in the previous season, beaten to a Champions League spot by Liverpool, was speculated to be improved upon yet mediocre business has somewhat dashed these aspirations in the minds of most.
Courtois is one of a number of talented Belgian stars to have come through Genk's youth system, where he was converted from a left-back before making his first-team debut aged just 16 years and 341 days.
If Courtois tomorrow says to me the same [as the agent], then I have to speak with my player, of course. "When you play for a big club you have to be ready to try to fight for the titles, and we're going to fight for that".
