David de Gea hasn't been the most consistent goalkeeper in the Premier League this season, but the Manchester United youngster is touted for big things, and he is desperate to prove he was worth the punt by Sir Alex Ferguson last summer.

De Gea had big shoes to fill, in the form of legendary stopper Edwin van der Sar, and with that has come the pressure to match.

But just as van der Sar has said in the past that he thinks de Gea has what it takes to be a top Premier League and international keeper, the 21 year old believes he has a long career ahead of him at United.

"I have every intention of spending many years at Manchester United," he said, as reported by Sky Sports.

"I want to go on to become a great United keeper and to earn and deserve respect. I want to help United make history."

De Gea made an incredible save at the weekend to help United to a 3-3 draw with Chelsea, and showed Ferguson just why he should someday be worth the gamble, and Van der Sar's Champion predecessor Peter Schmeichel himself has touted the starlet's skills and potential.

Spanish keeper and top Premier League star Pepe Reina has even weighed in on the debate this season, saying that De Gea is the future of Spain as well as United.

"It is typical that the critics smell blood when there is a mistake," he said last August, as reported by Goal.com.

"But if Mr Ferguson has put his trust in him by signing him then it seems logical that he will settle and be a quality signing for them."

Even Spain number one keeper Iker Casillas believes that De Gea will come good, but he needs time to mature first.
