Real Madrid and Atletico have already qualified for the semi-finals, while Barcelona attempt the miracle. They could be the third Spanish team to go through to the last four, as they will try to emulate the Madrid duo.
Yesterday it was Zidane and Simeone who were looking for a way into the next round of the Champions League, and today it is Luis Enrique's side who will have to give it their all if they want to pursue their dream of lifting the prestigious trophy.
They have a more complicated task ahead of them, needing to overturn the 3-0 defeat they suffered in Turin, while Atletico and Real Madrid both went into the second leg with an advantage.
However, the Catalans have already proved that they are capable, after the historical comeback against PSG which took them through to the quarter-finals.
Barca hope they can achieve another miracle and turn the tables on Juventus. The Italians are a strong and organised team that will try not to commit the same mistakes that Emery's side made at the Camp Nou.
At the end of the day, we will know if there is a 'Spanish hat-trick' this season, that is, three Spanish clubs in the final four of the competition. Meanwhile, Real Madrid and Atletico patiently await in the semis.
