Manchester United goalkeepr David de Gea will stay put at the Premier League club this season, manager Jose Mourinho said, amid media reports of continued interest in the 26-year-old Spaniard by teams including Spanish champions Real Madrid. In six years at United, De Gea has played 269 matches and won seven titles with his eye-catching displays gaining interest from clubs across Europe. Mourinho said United were open to a move for the keeper but clubs had withdrew their interest. "I can guarantee that he is not going this season," Mourinho told reporters in San Jose ahead of Sunday's pre-season International Champions Cup match against Real Madrid. <strong>READ MORE:</strong> "My feeling is it will very difficult for him to go. He is a very honest, straight boy. He was contacted for a long time, the club was closed and then we opened. I always have this feeling when a player has a desire to go, then I don't like to stop players. So we opened it and then they decided to close it. I see him really happy, focused, working better than ever and 100 per cent he stays with us." United playmaker Ander Herrera stressed the importance of his Spanish teammate, whose deadline-day deal with Real Madrid collapsed in the 2015 summer window. "If you lose the top three in any position, like David is ... it is a great loss," Herrera told British media. "We don't want to lose them ... For me, he's the best in the world, so I want to keep him here at United. "He is a goalkeeper who can give you points. That is very important. I want to keep him here, to play with him, because he's a fantastic keeper and also my friend, and I think you can see he's very focused on Manchester United."
