Isco will miss the Bayern vs Madrid second leg
The Spanish playmaker has a shoulder injury and came off at half-time in the first match
Real Madrid player Isco Alarcon went off injured against Bayern Munich in the semi-final.
Club medics' first reaction after inspecting Isco and his shoulder was not positive, and he is expecting to be out for the second leg on Tuesday.
Further tests will determine how serious the injury is. Zidane is already missing Nacho, Carvajal and Achraf Hakimi.
Bayern are 2-1 down and need to mount a comeback at the Santiago Bernabeu against the 12 time winners.
