Diego Costa hates life in England and is insistent on quitting Chelsea for a move away from the Premier League, according to the Sun.
The 28-year-old was left out of the Blues' squad for their 3-0 win with Leicester City, but manager Antonio Conte insisted it was due to injury rather than a reported move to the Chinese Super League.
Tianjin Quanjian are reported to be interested in bringing the Spain international to China on an £80 million deal, but despite Costa's desire to leave, Chelsea are not willing to sell their top scorer until the end of the season.
