Thiago Silva could leave AC Milan this summer if the price is right, according to his agent.
The Brazilian has been the subject of speculation linking him with some of Europe's biggest sides.
Silva has been a near ever present for Milan this season, with the Rossenari top of Serie A, and his agent Fernando Tonietto says the 27-year-old will only leave if Milan decide to sell.
"Thiago is happy with AC Milan, is a quiet person and is aware that he is playing for a great club," Paulo Fernando Tonietto told calciomercato.com.
"He is the world's best defender and therefore it is easy to link his name to Barcelona, Real Madrid or Manchester United.
"But no-one has called to discuss these options. It is just speculation.
"Could he end his career with Milan? He is 27 and has a four-year contract, so that could happen. If he does not stay, it will be because the club decided otherwise."
Silva signed a new contract during the summer, until 2016 after winning his first domestic honour in the Italian capital as Milan claimed the Serie 'A' title.
After ending Udinese's unbeaten home record this season over the weekend, Milan now lead the domestic table by two points over Juventus.
The former Porto midfielder, known for his tough tackling in midfield, has scored just twice this season for Milan, against Chievo in the league, and Barcelona in the Champions League.
While Silva's future appears to be safe, the club had to fight off interest from Paris St Germain in striker Alexandre Pato in the January transfer window and may have to do a similar thing to keep Silva at the San Siro.
