Real Madrid go into the second leg of their Champions League semi final against Juventus looking to overturn a slender deficit and end a 28-year hoodoo.
Not since 1987 against Napoli, have Los Blancos been successful over two legs in European competition against an Italian side.
It's something that Carlo Ancelotti will have to mastermind if he wants to ensure that Real don't end the season without a trophy, and also give Real a shot at becoming the first side in the modern era to retain the Champions League trophy.
Let's take a look at three things that could shape the outcome to this one...

The return of Paul Pogba
Real Madrid's midfield will have an entirely different proposition to deal with in this second leg.
The absence of Paul Pogba from Juve's line up in the first leg meant that there was a lack of penetration through the central areas from the Italians.
Most of the good work done by the Bianconeri came via the flanks and into Alvaro Morata and Carlos Tevez.

Pogba will ensure that any attacks are much more direct as he drives right at the heart of the Real defence.
Ancelotti has to make provision for the impact that Pogba will make otherwise the ex-Manchester United player will enjoy the freedom of the Santiago Bernabeu.
Allowed to roam freely, he will be decisive.
Away goal crucial
Thank god for Cristiano Ronaldo.
One of the easiest goals he will score could prove to be the difference in the tie.
Juve will likely come to Spain to defend their lead which is in itself a dangerous tactic against such a strong counter-attacking outfit.
In any event, if Ronaldo's defensive colleagues can shut up shop at the back, another score from right on the goal line will do very nicely again, thank you very much.
Morata with a point to prove
When Alvaro Morata made the breakthrough at Real Madrid, he was hailed as one of the stars of the future alongside the likes of Jese Rodriguez et al.
Yet, when push came to shove, he was shown the exit door and Juve have been the beneficiaries of his enviable skill set.
With national honours expected more regularly in future, where better to showcase exactly why he is considered one of his countries brightest young prospects than in the home of his former employers with the eyes of the football world on him.
Don't bet against Morata having a say in this one.
