If I told you that there was a goalkeeper who arrived in the Premier League at the age of 22, had won La Liga, the Copa Del Rey, a European trophy and played in a Champions League final with a Madrid club, chances are that you may well have shrugged your shoulders.
You probably would have until I told you that he accomplished all of these things with Atletico Madrid, a club whose wage bill was less than Fulham's in the 2013-14 season. Then this year, he displaces a Chelsea legend in Petr Cech to help his new side to a Premier League and Capital One Cup double.
I have always said, even as a Manchester United fan, that Thibaut Courtois is the Premier League's undisputed number one.
People will always say that David de Gea has saved United so many points this season while Courtois has been largely untested. While that is arguably true, it actually proves that the Belgian is the better of the two, given that he has had to maintain his focus in order to have the awareness needed for helping his side preserve their advantage.
Furthermore, unlike De Gea, he commands his area with a calm confidence not unlike the Spaniard's predecessor at Old Trafford, Edwin Van Der Sar. This should be no surprise given how the Belgian grew up idolising the Dutch legend.
If we were to contrast De Gea with Courtois, he may well go on to win everything at Real Madrid should he make the move, but given Barcelona's re-emergence and the fact that the Blaugrana have one of Europe's other emerging goalkeeping talents, it is highly unlikely for him to do so.
De Gea is not irreplaceable, although his predecessor pretty much is, unless Louis van Gaal can persuade Jose Mourinho to send his number 13 to Old Trafford.
Until then, let us all keep some perspective as United will be losing a keeper that is potentially the best in the world, but this is NOT like when they lost Van der Sar or Schmeichel. Two giants of men, who really were different class.
