Ghana international Kevin Prince Boateng has been excluded from the Barcelona team to play Real Madrid in the first of two classicos this week.
Boateng will not travel with the Catalans to the Santiago Bernabaeu for the second leg of the Copa del Rey semi final clash.
The on-loan Sassuolo forward has struggled to make an impact at the club since switching from Italy in the winter transfer window, making only two underwhelming appearances.
The 31-year old would return to Sassuolo after the end of his loan deal, according to reports in Spain.
Barcelona need a win to progress to their fifth final in five years, having won the last four editions of the competition.
