The Argentine was criticised by coach Michael Laudrup for his performance and Belenguer said: "He is ready to play (against Real Madrid).
"He will be successful over time. He has very good distribution and can spark counterattacks."
On Laudrup, the defender added: "We are all determined to row in the same direction. I'm not just talking about the players and coach, but also the president, the staff and directors. We all want to do better."
