Real Madrid president Florentino Perez has branded Cristiano Ronaldo "an undisputed legend of world football".

On Tuesday, the Portuguese was presented with his fourth Golden Boot award after leading the scoring charts in Europe for the 2014-15 season.

The 30-year-old has also become Real Madrid's all-time leading scorer this season and Perez has paid tribute to the attacker's achievements.

"Only a few days ago he became the top scorer in the history of Madrid. Cristiano is the only player with four Golden Boots, with his talent, devotion and passion for the ball. He is an undisputed legend of world football," AS quotes Perez as saying.

"He has a gigantic dimension and the numbers confirm the level of this player. He's won all trophies and no one should forget that he wants more. These awards haven't made him complacent and that connects with the identity of Real Madrid."

Ronaldo has scored 323 goals in 309 games for Real Madrid since joining from Manchester United in 2009, but has only won one La Liga title during his time in Spain.
