Diego Costa continues to stall on a new contract offer from Chelsea.

The Sun is reporting that the Spanish striker is yet to sign the deal that was verbally agreed around six weeks ago.

It is understood that the five-year deal, believed to be worth around £65million, remains untouched by Costa which suggests he may be planning a Stamford Bridge departure at season's end.

However, it is also suggested that Costa - who earns £150,000 a week in West London - wants to see what Eden Hazard is offered in his new deal before signing on with the Premier League title favourites.

Costa, 28, is still a target for mega rich Chinese Super League clubs and could also be the subject of another massive offer from the Far East.
