Casillas has no doubts: Courtois, the best in the world without a doubt.

Former Real Madrid and Spanish national team goalkeeper Iker Casillas said that "without a doubt" current Real Madrid goalkeeper Thibaut Courtois is the best goalkeeper in the world, highlighting his "maturity" and "solidity" that he transmits to the team ahead of Saturday's European final against Liverpool.

"The best in the world? Without a doubt, because the season he has had has been very good, he has established himself as a goalkeeper, you can see a very important maturity that he transmits to the rest of his teammates, if you have a goalkeeper like him you have a very solid phase," Casillas replied when asked at an event about whether Courtois is the best goalkeeper in the world.

The former Spanish goalkeeper took part in the presentation of the 'Mallorca International Football Cup Vicente del Bosque' tournament, which will take place from 28th June to 2nd July in Mallorca, where he gave his prediction for this Saturday's Champions League final against Liverpool.

"1-1 and we win on penalties. If Courtois saves one, that's enough for me," said Casillas, who will be watching his first final as a spectator.

"This is the first time I'm going as a fan, not as a player, but I'm excited, very happy to see that the club is still the best club in history because it's clear that when a team reaches so many finals, has so many great players and gives joy to its fans, it's a sign that something is going well, and that it is a world reference," he argued.

With three Champions League titles to his name, Casillas considered that for Real Madrid it is "a fetish competition".

"It's 13 Champions League titles, almost double the second, but it's true that for the club, for us, it's a special motivation, everyone has in their mind is to win the Champions League again," he added.

Casillas had words of thanks for Del Bosque at the presentation of his international tournament, whom he recalled that he has known "since he was eight years old" and that he played a key role in his transition from the youth system to the Madrid first team.

"Vicente, who was in charge of the youth system, felt that I had to keep progressing and get to the first team, but then you have to keep working," he recalled.
