AC Milan have turned down a "monster offer" from an English club for Brazilian teenager Alexandre Pato, according to the club's vice-president Adriano Galliani.

The 19-year-old striker has been strongly linked with a move to Chelsea, now managed by former Milan coach Carlo Ancelotti, but Galliani insists Pato will stay at the San Siro and will be offered a contract extension.

Pato has confirmed his desire to stay at Milan, a statement which delighted the Milan chief.

"Pato will get a contract extension," Galliani told the club's official website, www.acmilan.com. "I am absolutely delighted by Pato's comments.

"We have always spoken to Pato and the comments that arrive from other continents usually are mistaken. There were no doubts and there are no doubts regarding his future.

"The only offer that has arrived to our club was a monster offer from England for Alexandre Pato.

"I continue to believe that there isn't a player in the world that is as strong as him of his age.

"In any case, no one should worry because he is under contract through June 2012."

Pato finished as Milan's second highest scorer behind Kaka in Serie A last season with 15 goals in 36 appearances.
