Juventus boss Massimiliano Allegri admits focus can be difficult going into their Champions League semi with Real Madrid.

Juve meet Real this week.

"When you play in a Champions League semi-final, your mind is never completely clear," warned Allegri.

"You play with the awareness of your own strengths, the objective of reaching the Final and knowing you are among the top four in Europe.

"I'll tell them we are one step away from an extraordinary moment and therefore must play it with a relaxed mind and aware of our strengths."
