London, March 8 : Soccer aces Wayne Rooney and Cristiano Ronaldo are reportedly angry after being ordered to give a urine sample every day.

The Manchester United stars have allegedly been asked to submit bottles filled with their urine at their Carrington training ground in a bid to discover ways to improve their performance.

And the Premier League leaders, including the two superstars, were said to be annoyed with the new rule.

"During training when the lads get caught short, they use a bush as the main complex is too far away," News of the World quoted a source as saying.

"But they forget they still have to come in and give a sample, which means it can be a long wait for some of them!

"Afterwards the science boys have all these little bottles to work through. It's a bizarre sight-some joke they'd fetch a lot on eBay," the source added. (ANI)
