Goalkeepers are becoming more and more important in modern football.
Gone are the days that shot-saving was the only attribute that mattered.
Now, the ability with the ball at their feet and starting attacks is just as important.
And with goalkeepers becoming more important to how a side plays, there has been a dramatic change in the transfer market.
Gianluigi Buffon held the record transfer fee for a ‘keeper for 16 years when he moved from Parma to Juventus for £33 million.
That was finally broken in the summer of 2016 when Manchester City signed Ederson for £35 million.
Then, last summer, it was taken to another level with Liverpool snapping up Alisson for £67 million before Chelsea brought Kepa Arrizabalaga for £71 million.
Another goalkeeper on the move last summer was Thibaut Courtois - who left Chelsea for Real Madrid for £31.5 million.
But who is the best goalkeeper in world football right now?
In previous years, that answer may have been obvious.
Buffon was always a popular answer to that question before Manuel Neuer came along.
So, when Courtois was asked the million dollar question he had to pick three names.
"Ter Stegen, Alisson and Oblak,” Courtois answered, per AS.
"They are all great goalkeepers, but I do not know who is the best, I could not go for one, that depends on the defense and also on the whole team, I think I have already shown that I am at a high level.”
That’s very modest of the Belgian not to put himself in there.
But what about David de Gea?
The Spaniard is often considered the best in the world by football fans but it seems he’s not quite as highly-rated by one fellow goalkeeper…
