Manchester United midfielder Ander Herrera believes his side are not far off Real Madrid, who continue to be linked with goalkeeper David De Gea.
Last season’s Europa League champions have made a bright start in the Premier League, and the Spain international believes they are reaching the level of Los Blancos.
"David is really happy at the moment because we are fighting for everything," Herrera said.
"Real Madrid are going to talk about him every summer because he is the best keeper in the world. But we don't think we are far from Real Madrid.
"I respect all the keepers like Manuel Neuer, Gianluigi Buffon and Marc-Andre ter Stegen.But David right now is the number one in the world."
United will get to test themselves against some of Europe’s top teams, perhaps even Madrid, in this season’s Champions League, but first, they must prepare for a League Cup clash with Burton Albion on Wednesday.
