The five-time Ballon d’Or winner took just 445 games to win 334 games, whereas current Porto keeper Casillas needed 510 games to arrive at the same number.
Casillas, 37, admitted that he would have preferred that a Madrid player broke his record. However, he did state that Messi is worthy of being the record holder.
“I’d have preferred it to be a Real Madrid player, but these types of records are there to be broken and he has always done a great job,” the keeper told MARCA. “He deserves the recognition.”
“I am convinced that somebody will come who’ll also surpass his total,” he added.
After matching the record set by Casillas, Messi has a chance to break it on Tuesday when Barcelona take on Villarreal.
Lionel Messi continues to surprise the world football with his unique talent, but it’s not just fans shocked by his ability.
The Argentine icon scored twice as Barcelona stepped past Espanyol in the Catalan derby on Saturday.
His first was quite sublime, lofting a sumptuous free-kick right on the edge of the box. A Panenka, a chip or a caressed curler, whatever the description, the finish was superb.
And even Barcelona boss Ernesto Valverde was perplexed by the skill of Messi.
“I had no idea what he was going to do,” he said (h/t Goal). “I’d love to say it’s something we plan but it’s not like that, he did not pay attention to me and scored a goal.
”I suppose the goal will be awarded to Messi. It is not easy to beat the wall being so close to the goal.
“Some rivals put a player on the ground; others put a player on the goal line. For now, we are doing well like that.”
The 19-year-old is set to make a decision on his future with Ajax keen to wrap up his expected exit ahead of their titanic Champions League quarter-final clash with Real Madrid.
It was anticipated De Ligt would join up with colleague Frenkie de Jong at the Camp Nou with the midfielder completing his €75million move in the summer.
However, the centre-back remains open to the possibility of joining Serie A giants Juventus who head the list of potential suitors.
“[A move to Juventus] could happen, but there are others who are also interested,” he said via Tuttosport (h/t) Goal).
“We’ll see at the right time. At the moment I’m fully focused on Ajax and my agent [Mino] Raiola is taking care of the rest.
“Also, [Frenkie] de Jong hasn’t spoken to me about a move to Barcelona.”
With Samuel Umtiti’s future up in the air, signing a centre-back is top priority for Barcelona in the summer.
