When Manchester United handed Rooney a new five-and-a-half-year contract in February, worth a reported £300,000-a-week, eyebrows were raised as to whether the striker warranted that monumental deal.
However, Rooney has already proved his worth to David Moyes's side, having been one of the few positives in an otherwise wholly disappointing season at Old Trafford in the post-Sir Alex Ferguson era.
At 28, the England international is coming into the peak of his career as a striker, and will continue to play an integral role for the champions, as they look to re-establish themselves as a major player both domestically and in Europe over the coming years.
It would take a huge offer to convince Manchester United to sell, so it would be fair to say his valuation is over £100million.
