This is according to De Gea’s former United teammate Paul Scholes, who believes Cech could play in goal for the Red Devils for the next six years, despite the fact he turned 33 on Wednesday.
Cech is expected to leave Chelsea at the end of the season, after 11 years at Stamford Bridge, having lost his first-team place to the excellent Thibaut Courtois. While the world-class De Gea should become a Real Madrid player in time for the start of the 2015-16 campaign.
“If De Gea does go, United should sign Petr Cech,” Scholes wrote in his latest Independent column. “I remember the effect Edwin van der Sar had on the club when he arrived in 2005. United had struggled since Peter Schmeichel to find a really commanding goalkeeper.
“Fabien Barthez was the closest we got. Edwin came ready-made. He was a Champions League winner, he had four years’ Premier League experience with Fulham, and in the end our manager got six extremely successful years out of him.
“Edwin was almost 35 when he joined United. Cech has only just turned 33. He could potentially play another six years for United.
“There would be no concern about having to give him time to play his way into the position or the demands that the Premier League makes of a goalkeeper new to the country. United won’t want to lose De Gea but there is a solution in the offing.”
Cech is on United's shortlist
Cech is one of three goalkeepers Manchester United are reportedly considering should De Gea leave Old Trafford for the Bernabeu, along with Tottenham’s Hugo Lloris and Inter Milan’s Samir Handanovic.
Despite his advancing years, Cech remains a first-class goalkeeper. Jose Mourinho claimed earlier this season that the 33-year-old is still one of the world’s best three players in his position, next to Courtois and Bayern Munich’s Manuel Neuer.
But few would agree that Cech is currently a better goalkeeper than De Gea, who cleaned up at Manchester United’s end-of-season awards ceremony earlier this week. There’s a reason why Real Madrid, arguably the world’s biggest club, want the latter and not the former - and it’s not just because he’s nine years younger.
Victor Valdes could be the answer
But do Manchester United really need another top goalkeeper? After all, Louis van Gaal also has the hugely successful Victor Valdes, who Scholes fails to acknowledge in his latest column, at his disposal.
Valdes made his United first-team debut against Arsenal last weekend after De Gea limped off injured in the second half - and did not agree to join the Red Devils to warm the bench for 18 months.
Provided he can return to the level he was at prior to his serious knee injury - sustained over a year ago, while playing for Barcelona - Manchester United have no pressing need to sign another goalkeeper even if De Gea does leave this summer.
Although they may regret their decision to ignore Cech if Valdes is no longer as good as he once was.
