- Chelsea have told Tianjin Quanjian that Diego Costa will be allowed to leave in the summer
- Costa reportedly had a row with Antonio Conte after the club bid for the striker
- Tianjin Quanjian reveal Edison Cavani and Radamel Falcao had agreed to join the club
- The CSL side were forced to abandon their plans after a new rule by the Chinsese FA
The owner of Tianjin Quanjian has revealed that Chelsea have made it known Diego Costa will not be allowed to leave in the January transfer window.
Costa was dropped by Chelsea for the weekend trip to Leicester after a bust-up with Antonio Conte, amid suggestions that a £570,000-offer is on the table for the Spain international.
Shu Yuhui confirmed that his club are ready to spend mega-money on a move for a big-name striker - and that the 14-goal Premier League top scorer is at the top of their list.
The newly-promoted Chinese Super League outfit have already signed Belgium midfielder Axel Witsel, with Fabio Cannavaro the club’s new coach.
Yuchi said his side were close to wrapping up a deal for Edison Cavani but PSG blocked the move for happening.

"I made an appointment with Mendes and he came to my hometown to visit me. At that time, we were interested in signing Costa," he added.
"PSG told us Cavani would only be allowed to leave in June, even though the player himself was willing to join us.
"The same can be said for Costa because Chelsea would only let him leave in June. However, the new season of CSL will almost reach the halfway stage in June, we can't wait so long."
Additionally, Shu confirmed offers for both Karim Benzema and Radamel Falcao, as well as Benfica forward Raul Jimenez.
An offer of £45million for Falcao was lodged with Monaco, but rejected by the French table-toppers.
New rules limiting the number of foreigners ended the club’s interest in Falcao and Jimenez despite already drawing up contracts for the pair.
"Our club had a massive investment plan for the new season but it was tightened up by the new rules," Shu told Tianjin Sports Channel.
"We need an out-and-out striker so we made a bid for Benzema. We also made an attempt for Falcao.
"As a matter of fact, the club had even prepared the contracts for Falcao and [Benfica striker] Raul Jimenez. We had already reached agreement with them on wages and bonus.
"The pair were expected to sign the contracts, but the new rules forced us to give up on them.”
Costa's contract expires in 2019 and Chelsea remain concerned that Costa and his representatives are keen to explore several lucrative opportunities being offered in China.
