Manchester United midfielder Park Ji-Sung believes it was only a matter of time before Wayne Rooney blossomed into a world-class talent.
Having been with United since 2005, Park has seen at close quarters the startling progress Rooney has made.
Following Cristiano Ronaldo's world-record exit for Real Madrid last summer, Rooney has moved into another gear entirely.
He now stands just 10 goals adrift of Ronaldo's staggering haul of 42 two seasons ago and still has up to 13 matches left to reach it.
And Park, speaking at the announcement of a major sponsorship deal between United and Turkish Airlines, is not about to argue with anyone who puts Rooney right in the top bracket of players.
"People regard him as one of the best players in the world and that is absolutely right," said the South Korean star. "He has scored so many goals this season it is incredible.
"But everyone always knew he had the talent and ability to do it, so it is not a surprise.
"He was young before. He just needed experience. This season he has grown up."
