David de Gea says he felt unbeatable during Manchester United's 3-1 over Arsenal on Saturday.
The Spaniard single-handedly kept the Gunners at bay with 14 saves at the Emirates, a joint-record in the Premier League since records began.
Jose Mourinho heaped praise on the shot-stopper following his match-winning display, labelling him the "best goalkeeper in the world".
After United went 2-0 up within 11 minutes, De Gea was forced to pull out some brilliant stops as Arsenal launched a wave of attacks with only a close-range effort from Alexandre Lacazette early in the second half beating him.
When asked if he felt unbeatable, De Gea told MUTV: "Sometimes, you just start a game with a really good save, with a good feeling, you feel that [unbeatable] but we started the game really well, we scored two important goals and it's true that we lost a bit of a control of the game after, but it was a good performance."
Saturday's win earned United their fourth league victory in a row, the first time they have achieved that feat this season, setting them in good stead ahead of a tough week of fixtures which concludes with the top-of-the-table derby against Manchester City on Sunday, live on Sky Sports Premier League.
"We're really happy. I think they were both very tough games away from home so we now have confidence to play the last Champions League group game and after that, the derby," added De Gea.
"We're really confident now, we score many goals and this is the key as we look forward to the next game."
