The Spain international continues to be heavily linked with a summer transfer, but Tianjin Quanjian have distanced themselves from any possible deal

Tianjin Quanjian insist they have made no contact with Chelsea striker Diego Costa and are eager to avoid “overpriced signings”.

The Spain international remains the subject of intense speculation ahead of the summer transfer window, with a big-money move being mooted.

A switch to the Chinese Super League has been rumoured for some time, with lucrative offers reported to have turned Costa’s head in January.

He was to stay put and fire Chelsea to the Premier League title with a 20-goal haul, and one CSL side has now come to out to distance themselves from talk of any fresh interest from Asia.

In a brief statement published on Tuesday, Tianjin Quanjian said: “For the past six months, our club have not involved in any form of communication and negotiation with Diego Costa nor his representatives.

“Our club will draw up a rational transfer plan as an aim to improve the spectator experience of the Chinese Super League and meet its sustainability demands.

“We won’t take part in any unhealthy competition, thus preventing all overpriced signings.”

Tianjin Quanjian were reported to have a ‘verbal agreement’ in place with Costa at one stage, with a £25 million-a-year deal waiting for him in China.

They have, however, sought to play down the rumours on a regular basis over recent weeks, with a previous statement reading: “With regard to the widespread rumours that Chelsea's Diego Costa is expected to join Tianjin Quanjian, our club want to clarify that so far, we have not been communicating with Diego Costa regarding the transfer.”

There is still time for talks to be opened and it appears unlikely that the speculation surrounding Costa will be curbed over the coming weeks, with the latest reports suggesting that Atletico Madrid have once again expressed an interest in taking the burly frontman back to the Spanish capital.
