Despite Diego Costa's attempts at playing down transfer rumors to China with Instagram posts declaring his commitment to Chelsea, and all involved in the situation maintaining the same, and even recent rumors of a new contract extension, the possibility of the Brazilian striker leaving Stamford Bridge in the summer is not going away.
But even if clubs from far and wide, including China, may be knocking on Chelsea's door soon to try and lure Diego away via ludicrous amounts of money, one thing is certain. Diego is not learning Chinese, as revealed his Chelsea teammate César Azpilicueta.
"It's all rumours that come out. No, he is not learning Chinese. He is learning Spanish! He wants to win the Premier League with us and I don't see him, like you say, learning Chinese."
"I really hope he stays for a long time. He is giving so much to the team, not just goals. He helps create play. He is a reference player for us."
Of course, considering Costa’s relationship with the English language, him not learning a new language is hardly an indicator of any deal that may or may not be made.
In fact, Azpilicueta acknowledges it is ultimately a personal decision, just as it was with former teammate Oscar in December.
"It's a new market and there are many players that have decided to embark on that adventure. Each player has his own personal circumstances and different situations in his respective club and he makes that decision."

Unlike Oscar however, Diego remains very much a key player for Chelsea, leading the club's goalscoring charts and being a reference point for the team as highlighted by Azpilicueta.
