Wayne Rooney has rejected a staggering offer from a mega-rich China club, Football Insider sources understand.

Rooney has told friends that he’s fully committed to Manchester United and intends to stay until at least 2018 to fulfil his ambitions and break Bobby Charlton’s all-time scoring record.

The club – believed to be Shanghai Shenua – intend to take Rooney from England at the end of the season and have already tabled an offer that is said to be worth £500,000-a-week over three years.

However, a source close to the situation has told Football Insider that Rooney does not want to leave and is keen to extend his 12-year spell at Old Trafford, which will be marked by a testimonial match in his honour in the summer.

Tickets have not yet gone on sale for the event as there is a possibility Louis van Gaal’s team will have European qualifiers if they finish fourth in this season’s Premier League.

Rooney is central to the plans of the likely incoming manager Jose Mourinho, who tried to sign the striker in his second spell as Chelsea manager.

Knockout blow: Rooney is facing two months on the sidelines

The England and United captain, who turned 30 last October, will have three years left on his current £250,000-a-week deal at the end of the current campaign.

He is expected to be sidelined for up to two months with knee ligament damage sustained in United’s defeat at Sunderland last weekend.

Chinese clubs have flexed their considerable financial muscle in recent weeks with a glut of big-money signings including Ramires, Jackson Martinez, Alex Teixeira and Freddy Guarin.
