Diego Costa missed Chelsea’s 3-0 win against Leicester on Saturday at the King Power Stadium, due to a back injury according to official reports and on Monday was seen training alone at Cobham.
However despite the official line, there is speculation the Spain forward has fallen out with boss Antonio Conte after a training ground row, against a backdrop of a £30m-a-year offer from Chinese Super League club Tianjin Quanjian.
He was also spotted training alone on Sunday as the rest of the first team and management enjoyed a 48 hour break following on from their weekend success.
In order to play in next Sunday’s game against Hull City, Costa will need to prove himself in training before meeting with Conte to discuss the situation.
It is thought that Conte will refuse the Chinese offer but could be looking to give the green light to a summer sale, when he will be able to bring in a top class replacement to Stamford Bridge.
A formal offer from the Chinese side for the Blues leading scoring is expected this week but Conte is confident money is not everything
“The money is not everything,” Conte said. “When you play for a great team like Chelsea, you must be pleased. This league is really competitive. I think that this league can attract every player because this league is the first in the world for a lot of positive things.
“For this reason, I repeat these offers from China are not a threat for our league. Money is not everything.
“I have to look at the past, also in my squad. Oscar played with us, had a good offer from China, he went and I can see that threat for my players.
“But I think we’re a great club and it’s a great honour to play for Chelsea and for this reason I don’t see a threat for my players.”
