Manchester United won a Premier League away game for the first time since February after beating Norwich 3-1 at Carrow Road on Sunday.
United rode goals from Scott McTominay, Marcus Rashford and Anthony Martial to make it two wins from two road games in less than a week.
The video assistant referee (VAR) then controversially awarded United a penalty for a Ben Godfrey foul on Daniel James – with Krul stopping Marcus Rashford’s kick.
But Rashford scored with United’s next attack as he was left in acres of space by the Norwich defence.
United – who move up to seventh in the Premier League – were awarded a second penalty by VAR for a Todd Cantwell handball.
This time Martial took it and went the other way, and again Krul guessed correctly.
The Canaries, who remain in the relegation zone, had a couple of chances but United wrapped the game up when Martial clipped the ball over Krul after a good passing move with Rashford.
Norwich scored a late consolation through substitute Onel Hernandez, who took the ball off McTominay before running at United’s defence and shooting past David de Gea to becoming the first Cuban-born player to score a Premier League goal.
