Manchester United are set to hand their goalkeeper David De Gea a bumper deal in order to make sure his future lies at Old Trafford, according to the Mirror.

The 24-year-old's contract with his current employer runs down in 2016 and he has not signed a new deal. The Red Devils manager Louis van Gaal had earlier admitted the stopper will sign a contract extension.

The 20-times English champions have already offered him a deal, which will see him earn £120,000-a-week. Manchester City keeper Joe Hart signed an extension last month and he is on a £120,000-a-week payroll.

United now want to make the former Atletico Madrid star the highest paid keeper in the Premier League by paying as much as £140,000-a-week. The same report claims De Gea is set to be closing in on agreeing a new deal, which will keep him at Old Trafford till 2020.

The new deal will see United insert a £45m release clause to fend off any interest from Real Madrid. The Spanish international is on the radar of the 10-times European champions as he is expected to replace Iker Casillas for both club and country.

The former World Cup winner has also expressed his desire to play in the Major League Soccer (MLS).

"I have no problem of saying that I would like to play in the US," Casillas told The Wall Street Journal.

De Gea's agent Jorge Mendes has already hinted that a move to the Spanish capital is possible after claiming that "things change very quickly" in football.

The Madrid-born goalkeeper has been in fine form for United this season. His impressive display for the Old Trafford outfit has seen him attract interest from Real.

Should United fail to secure his services beyond his current deal before the end of the season, then De Gea will have one year left before the start of the next season. The Telegraph reports that Real are willing to sign the Red Devils star for nothing when his contract expires in the next 18 months.
