Michael Essien has missed Real Madrid's last few games because he has had an allergic reaction to medication, the club have revealed.
Madrid assistant coach Aitor Karanka revealed the information in a press conference on Friday, but did not give more details on the allergy, nor the medication Essien was allergic to. It was previously thought that the Ghanaian had not played recently because he had been experiencing muscular problems.
Karanka also gave details on the injuries of Marcelo and Gonzalo Higuaín.
"Marcelo could be out for a long time, it depends how it develops. He'll have his cast removed tomorrow. Gonzalo's problem is a muscular injury, so we have to treat it with caution and make a decision on when he returns."
