It's a lie [that we want to sell to sell him]. "I was asked before [during the January transfer window] why weren't we going to sign anyone", Zidane told reporters. I want Isco to spend all his career here.

"We have 25 players and everyone is important. Everyone is important", he said. "Winning the Champions League, that's what interests me more".
"The most important thing for me is the team". My intention was to succeed here, in the team that put their trust in me when I was at Malaga. There are many games. "I'm the one with a tough decision to make".
The midfielder has five goals and four assists in 18 league appearances this season, despite four of those coming from the bench, so there is little doubt of his talent.
