Juventus coach Massimiliano Allegri has talked up the importance of the second leg of their Champions League semi-final with Real Madrid on Wednesday.

The Italian champions hold a 2-1 lead from the first leg last Tuesday, and Allegri has challenged his squad to see the job through against the holders next week.

"We have to focus and treat it as it's the most important game of the year," he told reporters. "We have to try to secure qualification in Madrid - that won't be easy, for sure, but it could also take us to an unexpected final.

"Juventus are having a good spell from a physical point of view. The club hasn't played a game of this importance for 12 years but I believe we now have the experience and confidence to play well at this level.

"On Wednesday we will need to deliver a performance that is almost perfect. I won't say perfect because that is impossible in football but, for sure, we'll need our best performance to go through."

Allegri's side were held to a 1-1 draw by Cagliari on Saturday.
