The pair worked together during Jose Mourinho's time at the Italian club, where both achieved many success in Milan, including a treble winning feat in the 2009/10 season.
According to Mourinho, Muntari was also hidden to mimic him and there was a time he found out.
The Portuguese adds he made Muntari do an imitation of him in-front of his teammates ahead of their Coppa Italia final against Roma.
