David de Gea's agent, Jorge Mendes, has confirmed that they are in discussions with Manchester United to keep the 24-year-old at Old Trafford.
De Gea has been strongly linked to Real Madrid.
"I am negotiating with Manchester United about De Gea's renewal," Mendes told Spanish radio station Cadena Ser. "It is not true that De Gea has found a deal with Real Madrid. I'm negotiating with Manchester United his extension."
De Gea went from Atlético Madrid to Manchester United in 2011 for £17.8 million.
De Gea is out of contract in 2016 and could leave Old Trafford on a free transfer at the end of next season.
