Alex Ferguson has banned several of his star players from driving flashy sports cars the club's new shirt sponsor has offered to give them for free.
Chevrolet wanted to celebrate the fact that its name will appear on United shirts from next season by offering all of United's first-team squad their choice of a free car from the US manufacturer's range.
And, needless to say, almost all of them opted for the stunning, 638bhp Corvette ZR1, the flagship of the brand.
But it seems that while the United boss trusts players such as Danny Welbeck and Chris Smalling to drive his title charge, he doesn't trust them to drive a 200mph supercar. The Sun reports that United have banned any players under the age of 23 from picking out the Corvette.
"The model is dependent on their time at the club and driving experience," a United spokesman told the paper.
That means that older players, including 33-year-old Rio Ferdinand, will be able to power around in the £70,000 motor, which rockets from 0-60 in 3.4 seconds.
But the likes of Welbeck, Smalling, Rafael da Silva and Phil Jones will have to make do with something like the £8,475 Spark, which takes 15.5 seconds to hit 60 and won't even reach 100mph - let alone 200mph - unless driven furiously downhill with a hurricane blowing from behind.
