David de Gea's world-class save on Saturday against Liverpool made fans and the media alike all ask the same question: is he the best goalkeeper in the world?
When the Spaniard was first brought to Manchester United by Sir Alex Ferguson in 2011, initial signs suggested he wouldn't last long.
Mistake after mistake saw De Gea come under fire in the press to the point where he was labelled "error-prone" and even dropped by Fergie.
"I think young David made a mistake last week [against Fulham]," Ferguson admitted back in 2012. "He knows it.
"With the form he's been in, he's been making some fantastic saves but one error like that could have cost us the game."
How times change. Now 26 years of age, De Gea is widely regarded as one of the best goalkeepers in the world and a top target for Real Madrid.
His handling and positioning are bested only by his cat-like reflexes, as demonstrated during the 0-0 draw with Liverpool at Anfield.
De Gea produced an unbelievable save with his leg from close range to stop Joel Matip from making it 1-0.
So, is he the best? That was the question posed to Jamie Carragher and Peter Schmeichel on Monday Night Football ahead of Leicester City vs West Brom.
Three goalkeepers were discussed on Sky Sports - De Gea, Manuel Neuer and Thibaut Courtois - but Carragher was in no doubt that De Gea is No.1.
"I think he is," said the Liverpool legend. "From what I see, if I was picking a world XI then David de Gea would be in it.
"We are lucky that we have the Premier League's greatest-ever goalkeeper here (Schmeichel), but I think De Gea is second."
Carragher made the bold claim that De Gea is not only the world's best right now, but the second best in Premier League history behind Schmeichel.
But Schmeichel, rather surprisingly, had other ideas. According to the Dane, Neuer is the world's No.1 goalkeeper at the moment, not De Gea.
"My favourite goalkeeper at the moment is Manuel Neuer and has been for a long, long time," he argued. "That's because of the style of goalkeeping that he gives to the world.
"I watched him when he played for Schalke at Old Trafford and my eyes were like this [thinking] who is this young kid? He is brave, he is playing so far out of his goal.
"He is one of the very few goalkeepers who is actually off his line, far off his line, challenging the opposition and bringing the game to him. I like that."
Picking between De Gea and Neuer is no easy task - they're both world-class - so clearly it all depends on your preference of style.
