The 26-year-old Argentina international is under contract until 2015 but he will be allowed to leave during the upcoming transfer window if a club meets his buyout clause
The Argentina international still has another three years to run on his current contract with his Belgian employers but he has made it clear that he wants to leave for pastures new this summer.
Biglia has been heavily linked with Madrid in recent months and, while he claims that he is also being closely monitored in north London, his preference is for a move to the Spanish capital.
"There has been contact with Real Madrid and Arsenal and we are waiting," the midfielder is quoted as saying by Todo Mercado.
"If Real Madrid decides to make an offer, everything else would be put in the background. We'll see what happens.
"I have a contract with Anderlecht until 2015, but the club know that I intend to leave. We have negotiated my buyout clause and if a club comes to pay it, Anderlecht will let me go."
The 26-year-old, who has been capped six times by his country, made his name at Independiente before moving to Belgium in 2006.
