Kiko Casilla says Real Madrid need the “magic” of attacking midfielder Isco amid frenzied speculation over his future at Santiago Bernabeu.

The Madrid goalkeeper joined Zinedine Zidane in urging Isco to stay at the club after he produced another magnificent performance in Sunday’s 3-0 LaLiga win over Alaves.

The 24-year-old scored the second goal for Zidane’s men with an impressive finish five minutes from time and dictated much of his side’s play, recording a season-high 101 touches.

Isco now has five goals in his last six league starts, but spoke earlier this season of his desire to play more regularly and has been linked with a shock move to rivals Barcelona when his contract expires in 2018.

But Casilla thinks Isco is a natural fit at Madrid, telling reporters: “He is phenomenal. He showed that with Spain and he repeated that with another great game.

“He showed great composure to score his goal. We need him and I think he looks very comfortable here at Real Madrid.

“He is very important, for that different magic he brings. From now until the end of the season we are really going to need him and he knows that.”
