He is a very good footballer, he has shown that, and can always show that, so [the report] is a lie.
That has led to inevitable speculation in England that Isco - who came off the bench for Gareth Bale and scored Real's second goal in their 2-2 draw at Levante last weekend - could be bound for the Premier League.
With Liverpool having failed to sign a replacement for Philippe Coutinho in January, getting in a player to fill his hole in the lineup is going to be a priority this summer, and Isco would fit the bill-plus Liverpool have the cash to win any race for him.
"It's good you ask me about that". Things aren't going the way we want, that's true, but at the end of the day we know who we are, that when the tough gets going we have to stick it at it by working hard and keeping a positive attitude. He's proven that in the past and will do that again.
"I want Isco [in my team] and I want him to spend his whole life here. Hopefully we won't hear any more of this".
Nevertheless, Zidane was keen to point out that his backing for Isco did not mean a guaranteed run of starts, given the competition for places in his Madrid squad.
Not only that, he has explained that the player will get game time, as will numerous squad because they have so many games coming up.
"There's 25 of us".
He continued: "Zidane is a huge admirer of Isco's style of play and what he can offer the team and for this reason opted to keep faith in the player deeming that he would be instrumental in the creative play of the side".
"I have to pick a team".
"I get asked about Isco and I'm pretty sure I'll get asked about Asensio and [Dani] Ceballos and players who might play less than their team-mates".
Arsenal and Liverpool are among the clubs ready to battle-it-out over the signing of Isco as Real Madrid prepare to cash-in on the attacking midfielder this summer, according to reports in Spain via the Express. The most complicated thing for me is to make the line-up.
