FC Rostov coach Kurban Berdyev has revealed what the mysterious gift he received from Jose Mourinho was.
The Manchester United boss sparked interest when he was pictured handing over a black box to the away dressing room prior to his side's Europa League second leg at Old Trafford.
The Red Devils went on to win the tie 1-0 and progressed to the quarter-finals thanks to a 70th minute Juan Mata goal.
But since the clash, the contents of the box have been shrouded in mystery... until now.
