Anderson has signed a new contract with Manchester United, committing the midfielder to the Premier League club until June 2015.
The 22-year-old Brazil international joined United on a five-year contract from FC Porto in 2007.
Having returned from long-term knee problems that ended his chances of going to the World Cup, Anderson has featured regularly for United in recent weeks.
He netted only his second goal for the 18-time English champions last week to secure a 1-1 draw with Valencia in the Champions League and featured in a 1-0 victory over Arsenal on Monday.
United manager Alex Ferguson said on the club website that “Anderson has developed tremendously since joining the club and he has fantastic potential.”
