Since taking over in 2014, Allegri has led the 'Old Lady' to two runners-up spots in the competition in three years.
But after our stunning comeback in Turin left our tie with Juve in the balance, Allegri has underlined just how important tonight's second leg is to his side.
“I don’t know how Spurs are going to play. We’ll have to be a lot better technically than in the first game, particularly the second half. For us it’s like a final," said the respected coach, who was in charge of AC Milan when we knocked them out of the Champions League at this stage in 2011.
