The Spanish ace was approached by Real Madrid, but has never even considered quitting Barca, according to his father
The 20-year-old put an end to all speculation about his future by signing a two-year contract extension, which will tie him down to the club until 2015.
After playing an instrumental role in Spain's successful campaign at the Under-21 European Championship in Denmark, Real Madrid were mooted as a possible destination for Alcantara, and his father has now confirmed that the capital club did come knocking.
"They [Real Madrid] asked about him, just like many other European clubs did," Mazinho told Ona FM.
Alcantara's father added that signing a new contract was an extremely simple process, saying: "They called us on Tuesday and they had the contract almost completely written. We came to an agreement quickly."
Despite all the strong suggestions about Alcantara's future, Mazinho stressed he always knew the player would not move on, and went as far as to say his son wants to stay at Camp Nou until his playing days are over.
"He is delighted with his new contract, he wants to stay at Barcelona for the rest of his life," Mazinho added.
"I never doubted that Thiago would stay. The club had always called us, given us that peace, that security, and had always wanted to end all that story."
