​Premier League giants Chelsea have reportedly lost patience with striker Diego Costa and will consider selling him to Chinese Super League club Tianjin Quanjian in the summer claims ​London Evening Standard.

The 28-year-old has had a brilliant season so far, scoring 17 league goals in 26 appearances as he led Chelsea's charge towards the title. However, he has struggled for form over the past six games, failing to make an impact, with many attributing it to due to interest from the Chinese side.

Tianjin Quanjian had reportedly offered the Spaniard a contract in the excess of £570,000-a-week in January and were ready to offer the Blues 80m for his services. The team management had rebuffed the offer as they were happy with Costa who was in prime form at the time.

The club though has apparently had a change of heart due to Costa's insistence of an increase in his £150,000-a-week salary and with the Blues keen on signing Everton's Romelu Lukaku or Real Madrid's Alvaro Morata in the summer, it looks like the Spaniard could be moved out from Stamford Bridge.

The 28-year-old has scored 55 goals in 109 appearances in all competitions since joining them from Atletico Madrid in 2014, winning one Premier League title and one League Cup so far.
