The retired midfielder has hailed his former teammate's ability after the goalkeeper was dropped in favor of Antonio Adan
Jose Mourinho opted to start Antonio Adan for the 3-2 defeat to Malaga, with the club captain forced to settle for a place on the bench.
The Portuguese has since defended his decision and insisted the move was purely down to footballing reasons and not because of a problem between the pair, with Guti offering his backing to his former teammate.
"It's not about choosing between Iker or Mou, the most important thing here is Real Madrid. It's fundamental that the team return to normal as soon as possible," he told AS.com.
"Iker knows that he is the best goalkeeper in the world and that everything will return to normal soon."
The defeat leaves Los Blancos in third place and 16 points adrift of league leader Barcelona.
