AC Milan vice-president Adriano Galliani insists his club will reject all offers for much sought-after defender Thiago Silva, who is a reported target for Premier League champions Manchester City.

Thiago Silva, 27, has been linked with a move away from the San Siro this summer, with a number of top European clubs keen to acquire his services.
On Wednesday, City striker Mario Balotelli was forced to quash persistent rumours that he could be included in a swap deal for Thiago Silva and now Galliani has stated Milan's desire to retain the Brazilian's services.
"We will do all that is possible and impossible to resist temptation,'' Galliani told Gazzetta dello Sport. "Thiago Silva is happy to remain in Milan. He has a contract until 2016.''
Barcelona and Paris St Germain are also among the club's believed to be chasing Thiago Silva and Galliani said: "There is a true siege for him. It seems every club wants him, rich clubs and their owners.''
Thiago Silva will be in action in London this summer, with the defender set to play at the Olympics with Brazil.
"Thiago asked and obtained the authorisation from us to go to the Olympics,'' Galliani said. "We evaluated that it's better for us to have a player who is happy rather than unhappy.''
The centre-back joined Milan in 2009 from Fluminense after previous unsuccessful spells in Europe with Porto and Dynamo Moscow, and made 27 league appearances for Massimiliano Allegri's side this season.
Galliani also revealed they club would not acquire the full rights of Italian midfielder Alberto Aquilani or Argentinian striker Maxi Lopez.
The Rossoneri can exercise that option at the end of the month, but Galliani said: "Aquilani will not be bought at the end of May. We will see if we can find other solutions in June.
"For the time being, even though we are happy with him, we cannot buy Maxi Lopez.''
Milan signed Aquilani from Liverpool on a season-long loan agreement last summer, while Lopez arrived at the San Siro on loan from Serie A rivals Catania in January - scoring one goal in eight league appearances.
