Real Madrid chief Emilio Butragueño has failed to quash the rumours over the signing of Manchester United goalkeeper David De Gea before the end of the transfer window, despite the impressive performance of Keylor Navas in the 5-0 victory over Betis on Saturday 29 August. Former Liverpool and Chelsea boss Rafa Benitez, meanwhile, was also coy when asked whether the Costa Rica international stopper will stay at the Santiago Bernabeu this summer amid the potential arrival of the mancunian number one.

De Gea has heavily linked with a move to the Spanish giants since later last season he rejected a renewal offer to renew his current deal at Old Trafford which is set to expire next summer. United, however, have since held his departure by asking around £35m ($53.8m).

But with relations between De Gea and Louis van Gaal broken, Daily Express reports that the Premier League giants will finally accept a lower offer of around £25m to part ways with the keeper before the end of the transfer window in Spain on Monday, 31 August. Butragueno and Benitez have now failed to quash the speculations despite Navas performance against Betis, stopping a penalty to secure his second clean sheet in two games, reopened the debate on whether the Spaniards need De Gea.

Asked after the game about the potential signing of the United keeper following Navas impressive performance, Butragueño was quoted by AS saying: "We don't speak about players from other clubs. We are happy with our squad.

"Navas' performance is a prove of how good he is. We are very delighted with him and the fans have showed it. He has had a remarkable game. He has had an impact in the final score with a shiny performance and we have to highlight it."

But when Benitez was questioned whether he can confirm Navas is going to stay at the Bernabeu or if De Gea will replace him, the boss said: "What has been my answer over the past few weeks about the three goalkeepers? I am delighted with the three goalkeepers and I just want to enjoy this 5-0 win. I am happy with all of the players I have – very happy".
