Former Tottenham boss Harry Redknapp expects Diego Costa to leave Chelsea.
Costa has been offered £30m-a-year to go to the Chinese Super League and has had a bust-up with Chelsea staff over the last week.
"Obviously he fancies it, 'I'll have three or four years of that'," he said on talkSPORT. "It's a backward step in football but it's the money.
"If he goes out there for four years he'll come back with over £100m. There's no real challenge.
"Even the other boy Oscar said he came for the money. You don't leave Chelsea to go to China for football.
"I would think it is about money. They don't grow up wanting to play for Chelsea.
"They're not bothered about the loyalty of the club."
