No side has ever come from more than a goal down after the first leg of a Champions League semi-final, though Atletico midfielder Koke is not giving up hope that they can become the first club to do so: "We never give up and we always pick ourselves up after we've been knocked down". Live coverage of the game will be on BT Sport 2 and BT Sport 2 HD. We'll have to attack, but keep a cool head, because by playing like madmen we can concede two or three goals in a row. Or when you see how they scream at each other for the good of the team at freekicks - it was a lesson for us. This match will decide which team will move one step closer to their dream of winning the champions league.
Madrid hold a 3-0 first leg lead thanks to a Cristiano Ronaldo's hat-trick at the Santiago Bernabeu last week Tuesday.
"We must be very focused because Monaco have nothing to lose and they will play an open and carefree match, with very talented players who can cause all sorts of problems".
In terms of his team selection, Allegri added that the majority of his first-choice players are fit.
Juve have one foot in the Champions League final too, after nullifying the attacking threat of Monaco in their own back yard to win the first leg 2-0.
This is the second time these sides have met in a Champions League semi-final, Juventus securing their passage to the final with a 6-4 aggregate victory 19 years ago before losing to Real Madrid in the final (1997/98).
While Juventus are unquestionably good enough to frustrate any opponent in the Champions League final with their rock-solid defence, doubts remain over their ability to be ruthless against the very best when it comes to finding the back of the net. They ended up losing to Jose Mourinho's Porto in that match and now they have to defeat a Juventus team who have kept six successive clean sheets in the competition.
Higuain, in contrast, was at his clinical best, finally taking his domestic form on to the biggest stage with his first goals in a Champions League knock-out game in four years.
Gonzalo Higuain scored the all-important opening goal against AS Monaco in the first leg.
bet365 Sports is in favor and expecting a Juventus win, posting at 1.61. They have scored 150 goals in all competitions this season and are about to win the French title.
The last time they were beaten there was August 2015 - when Monaco wonderkid Kylian Mbappe was still turning out for the under 16 team.
"Everyone would like to get to the final".
They looked out of sorts in a 1-1 draw with local rivals Torino at the weekend but, with matches to spare in Serie A, Allegri rested a string of key players ahead of today's encounter and Sunday's potential title-clincher at Roma.
