The Togo striker had to be restrained by players and staff after bursting into the Italian's training ground office with proof of a torn muscle, an injury Mancini had initially brushed off as nothing more than a dead leg.
Former Arsenal man Adebayor was dismayed to his boss thought he was feigning injury.
