Manchester United players have been ordered to drive only Chevrolets when visiting the club's facilities.

The motoring giants were concerned the club's biggest stars were shunning the free vehicles they had supplied, in favour of driving their own Porsches and Range Rovers to and from work.

"It was pretty embarrassing when they motor firm had handed over all these free cars and no one wanted to drive them," a source told the Daily Star on Sunday.

"Now the lads have been asked to take them for a spin every now and again so they get pictured behind the wheel of a Chevy.

"They might not be Porsches but they are lovely cards and the average United fan would kill for a free motor. So far stars such as David De Gea, Jonny Evans, Juan Mata and Antonio Valencia have been spotted driving the cars to the training ground."
