Manchester United striker Wayne Rooney has undergone more hair surgery!

The Daily Mail says the 27-year-old, who has been strongly linked with moves to Premier League rivals Arsenal and French big-spenders Paris St. Germain, has had a second 'top-up' hair transplant procedure, just two years after the first operation.

Rooney went through a nine-hour operation last weekend as a follow on from his 2011 surgery at London's Harley Street Hair Clinic.

According to the clinic, the second procedure is 'standard', and is part of the £15,000 Wayne paid for the procedure two years ago.
