Serie A top scorer Quagliarella has earned his recall to Roberto Mancini's new-look Italy thanks to his 21 goals in 28 league games, two more than Portuguese star Cristiano Ronaldo has managed for Juventus.

The Sampdoria player becomes the oldest player ever to score for Italy aged 36 years and 54 days, overtaking Christian Panucci, who scored aged 35 years in 2008.

"I want to thank my teammates. After the two goals they encouraged me to get a third one too, but it didn't happen.
"I thank Jorginho and (Leonardo) Bonucci because they're the penalty takers and they told me to kick.
"They said: 'The evening is yours, you kick it'."
