The 25-year has been criticised for his goalkeeping errors over the past few months – ever since the Champions League final against Real Madrid, that the Reds lost 3-1.
Casillas, however jumped to the defence of Karius after he had made yet another error in a pre-season friendly against Borussia Dortmund on Sunday that led to a goal.
On Tuesday, the Spain legend tweeted his own blooper reel that included errors Casillas had made in big Champions League and international matches during his career.
The World Cup winner wrote: “Behind each one of us is a person. Raise your hand whoever has never made a mistake. Learning from mistakes makes us stronger and accepting them more human. #Ialsomakemistakes.”
Detrás de cada uno de nosotros, hay una persona. Que levante la mano quien no haya fallado alguna vez. Aprender de nuestros errores nos hará más fuertes y aceptarlos más humanos. #yotambienfallo pic.twitter.com/jwLOdicfTh— Iker Casillas (@IkerCasillas) July 24, 2018
