The day of 3 August could be pivotal to how Wayne Rooney and Manchester United respond to a reported £27million bid for the striker from a Chinese Super League club.

That is the date of Rooney’s planned testimonial at Old Trafford against boyhood club Everton, with all proceeds going to charity.

According to the Mirror, an unnamed club are said to be prepared to offer the United skipper a staggering £500,000-a-week, three-year contract to make him the face of the mega-rich China league.

The club – believed to be Shanghai Shenua – intend to take Rooney from England at the end of the season and have already tabled a formal offer.

However, United have decided to mark Rooney’s 12 years of service with the 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.

Another factor is where Rooney would fit into the plans of likely incoming manager Jose Mourinho, who tried to sign the striker in his second spell as Chelsea manager.

Rooney, 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.

After 12 years service, it would be a remarkable deal for United if they were to recoup the fee they paid Everton for Rooney as a teenager.

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.
