Iker Casillas would always remain one of the greatest goalies in history for both Real Madrid and Spain.

And yet, his best is still on the way as he is currently progressing in an excellent start to the new season which has seen him concede no more than four goals in nine games for Porto.

This run of form puts him amongst the best goalkeepers in Europe with retirement not an option at the moment. So far as well, Jeroen Zoet, goalie for PSV is the only keeper that has conceded such few goals as Casillas, which make this record as good or even better than any of his starts in any season for Real Madrid.

The only time Casillas ever conceded fewer goals in the first nine games was back during the 2004/05 season, thus putting him at his consistent best.

“I feel better and better,” Casillas said. “After a difficult first year, I’m very happy here at Porto and in this city.”

Former goalkeeper for Porto, coach Juan Carlos Arevalo knows Casillas quite well and has put forward a reason behind his uptick in form.

“What’s key, more so than just his talent, is that he is now communicating very well with his defence, and he is able to use his experience to prevent dangerous situations,” Arevalo was quoted to have said.

“Casillas is amongst the best keepers in history and is still an icon for Spanish keepers everywhere,” Arevalo continued. “He takes good care of himself and is always thinking about football.”

Arevalo, who had also worked with the goalkeeping staff for Julen Lopetegui was of the opinion that a possible return for Iker Casillas to the Spanish squad might not happen as the National side’s coach had chosen a goalkeeper in David de Gea. This might mean that Casillas’s time with the national team is over.
