Juventus coach Max Allegri says their Champions League clash with Atletico Madrid isn't about just Cristiano Ronaldo.

Allegri says Ronaldo will need support as they chase down Atletico's 2-0 lead.

“We've got to give something more, but that just means everyone giving what they are capable of. The emotional approach is very important, games are strange and we mustn't stop if there are difficulties.

“People say 'you have to give 110 per cent,' but that's impossible. The important thing is to end the game, either after 95 minutes or 120, without regrets.

“Ronaldo is a player with such Champions League experience that having him with us in these circumstances is a great advantage."
