Zenit St Petersburg coach Andres Villas-Boas says Real Madrid star Cristiano Ronaldo has stepped up his game in the past two years.

AVB feels Ronaldo has made a conscious effort to improve even his body language while with Real.

"He even changed his body language on the field and that supports him further still, both as a player and as a sports personality," he said to TVI.

"In the last two years, I have seen in Cristiano Ronaldo a change of attitude and an incredible dedication to his profession, an impressive will to win, even if his value has been questioned due to the quality of his closest rival (Messi)."
