Iker Casillas has named who he feels are the five best goalkeepers on the planet.
The Real Madrid legend knows a thing or two about shot-stopping given he spent well over a decade as first-choice keeper at arguably the biggest club in the world.
And it's always nice when someone with a wealth of expertise weighs in on a matter such as this because, let's face it, barely anyone really understands what it takes to become a world class keeper.
Sure, we've all played football plenty throughout our lives but goalkeeping is like a whole different sport all together.
If you think about it, it's actually more like a cross between cricket and gymnastics than football.
And for that reason, unless you specialised there, it's pretty impossible to understand what is required at the very top level in that position.
Casillas was asked by Diario AS' YouTube Channel to name his top five and so we've included a summary for you below.
5. Manuel Neuer
The iconic Bayern Munich stopper might just be remembered as the finest of his generation when we look back, so it seems only fitting that he's included in Casillas' top five.
Neuer was the first to really perfect the art of the 'sweeper keeper' and plays the role to great effect to this day, despite now being the ripe old age of 36.
Undoubtedly one of the very best to ever do it.

4. Marc-Andre Ter Stegen
Another German in at number four then, although it's fair to say that Ter Stegen has never reached the heights of his compatriot in his career to date.
It's actually rather surprising that Ter Stegen makes this list - especially ahead of Neuer, who remains captain of the German national team to this day, keeping his place in the starting XI at Ter Stegen's expense.

3. Jan Oblak
If this list had been formulated last summer then it would have been a fair shout to include Oblak at number one.
The Atletico keeper boasted an exemplary record for many years at Atletico but has let his form slip across the past 12 months, there can be no denying that.

2. Ederson Morales
Manchester City's Brazilian keeper is another interesting inclusion. Whilst he's certainly brilliant with his feet, there have been question marks posed recently about his shot-stopping ability - which, naturally, should be a keeper's bread and butter.
The fact he's included over his compatriot, Alisson Becker, also raises a few eyebrows given the Liverpool star keeps Ederson out of the Brazil squad.
But, then again, we aren't the expert here and Casillas knows what he's talking about.
Man City's Ederson won the Premier League Golden Glove.
1. Thibaut Courtois
Little bit of bias there, Iker? Na, only kidding, we feel like Courtois is a totally justifiable selection for the number one spot - did you see him in last season's Champions League?
The Belgian was absolutely immense and aside from Karim Benzema, might have been the most important factor in Los Blancos' European triumph.
