Real Madrid have reportedly made it clear that they would consider using Keylor Navas in a deal for Manchester United goalkeeper David de Gea.
The speculation surrounding the future of De Gea has forced Louis van Gaal to leave the Spaniard out of his side for the first two Premier League games of the season, and Real are still believed to be confident of securing his services before the end of the transfer window.
United signed Sergio Romero earlier this summer to improve their options as they prepare to sell Victor Valdes, and the Daily Mail claims that Navas may move to Old Trafford should they finally come to an agreement with Real.
Navas moved to the Bernabeu from Levante last summer following his impressive performances for Costa Rica at the World Cup, but he also faces competition for his place after Kiko Casilla arrived earlier in the window.
It has previously been reported that Real would have to offer a record fee for a goalkeeper to sign De Gea, who has just one year remaining on his deal.
