Isco's frustration appeared to boil over during Real Madrid's 3-0 home defeat to CSKA Moscow in the Champions League on Wednesday.
Isco was seemingly involved in an angry confrontation with the Bernabéu crowd as Real Madrid fell to a heavy defeat to CSKA Moscow in the Champions League on Wednesday night.
"What do you want? - Isco to Bernabéu fans
After seeing a shot deflected behind by a CSKA defender early in the second half, the Spaniard approached referee Artur Soares Dias to complain about his failure to award a corner, before apparently turning to the Madrid fans and shouting: "What do you want?"
Fans respond by whistling Isco
A section of the Bernabéu support responded by whistling Isco, whose Madrid team-mate Marcelo later revealed that the midfielder turned down the captain's armband when the Brazilian was replaced by Dani Carvajal later in the match.
