And the ?17.8million summer signing reckons he can go on to eclipse Edwin van der Sar's achievements.
The Dutchman won 11 trophies at Old Trafford before De Gea, 21, arrived from Atletico Madrid to replace him this term.
But De Gea has committed a series of howlers ? including gifting Grant Hanley a shock winner for Blackburn on Saturday.
The new boy has let in 26 goals in 19 games while big rival Anders Lindegaard has kept six clean sheets in a row.
But De Gea said: "Hopefully, I'll equal or even surpass the performance and contribution Edwin made."
The Spaniard let a long-range shot from Manchester City's Edin Dzeko squirm under him on his United debut at Wembley in the Community Shield.
But he seemed to have got mistakes out of his system before his Rovers ricket.
He said: "Let's face it, all keepers make mistakes once in a while, and none of us like it when we do.
"Errors happen but I've gone on to be more confident.The style of play here is more physical and as a goalkeeper you've got to be right on it."
Boss Alex Ferguson has confirmed Wayne Rooney will be back in the side to face Newcastle tomorrow.
The striker was dropped for the Blackburn match and fined a week's wages over his lacklustre showing in training after a night out last week.
But Fergie said: "Wayne will be available.
"We had a few training sessions and he missed a few.
"You've got to be fit to play in this league. You can't miss training sessions."STRIKER Josh King, 19, will return to Old Trafford having played just twice in an injury-hit loan spell with German side Borussia Monchengladbach.
