The Spanish footballer couldn't take any more abuse, since he was booed by Los Blancos' supporters every time he came in touch with the ball.

The game between Real Madrid and CSKA left a number of reasons for Los Blancos fans to be worried about their future in the competition. To make matters worse, things don't seem to be on the best terms between the fans and one player that should step up to lead the team when things get tough.

That player is none other than Isco, who has been involved in a number of controversies all season long for his poor form and for being relegated to the bench since Solari's appointment as coach. Today, the former Málaga footballer entered a war of words with his team's fans, since he had enough of them complaining about his performance.

Right after a good play by Vinicius, the player's shot was deflected by a CSKA player, with the ref making a wrong call by giving the Russians a goal kick. Isco looked at the goal line ref to complain, and then directed his anger to Real Madrid's supporters by furiously asking "what do you want?"

This incident may cause one more problem between the footballer and his coach, especially since they are not believed to have the best relationship. With the winter transfer window right around the corner and a handful of incidents such as this one in his record, it wouldn't be a surprise to see Isco living his final weeks as a Real Madrid player.
