Atletico Madrid forward Diego Costa is reportedly unhappy at the club and is keen to move to the Chinese Super League.
According to El Mundo (h/t Football Espana), the former Chelsea man isn't content with his contract in comparison to star striker Antoine Griezmann.
Costa is said to earn around €8.5 million (£7.6 million) every year with the Madrid outfit, whereas the new deal Griezmann signed in the summer sees him take home a staggering €25 million (£22.25 million).
It's added that Costa has asked his agent to look into possible destinations for him as a result, most notably a January move to China.
