In what has become one of the most open final stages in recent years, the 2014-15 Champions League trophy could end up in numerous destinations, according to current form.

Bayern Munich shockingly fluffed their lines when visiting Porto in the first leg, making the sort of defensive errors you do not associate with the Bavarian superclub. 

However, Bayern's single away goal, collected by Thiago Alcantara, could yet be the difference if the Bundesliga champions can claim a 2-0 home win—which is well within their ability. 

Guardiola's team are still the most likely side to challenge La Liga's contingency of clubs going for the famous old trophy this season, but Bleacher Report's Sam Tighe thinks Bayern's current injury list could cost them dearly as Porto look to park the bus:

Barcelona silenced their detractors in Paris as they expertly dealt with a PSG team with high ambitions. 

The game saw Luis Suarez step forward and grab the plaudits, with the Uruguayan saving his best form for the end of the campaign. 

The former Liverpool icon netted twice in the first-leg match and all but guaranteed the Blaugrana a safe passage into the semi-finals. 

Juventus look set to have their most successful Champions League campaign in recent memory as they try to dispose of Monaco in Turin.

A penalty from Arturo Vidal gave the Old Lady a slim first-leg advantage over the principality club, but Monaco will be encouraged by their previous-round elimination of Arsenal, where they proved they can raise their game to unexpected standards.

Despite the intrigue in these three ties, all eyes will be focused on the Santiago Bernabeu as Real Madrid look to defeat neighbours Atletico in a replay of last season's ill-tempered final. 

Diego Simeone's men have failed to hit the heights of last season but have been Carlo Ancelotti's side's masters this term, defeating Los Blancos on four occasions, per WhoScored.com.

This included the recent February 4-0 destruction at the Calderon, lead by the brilliant Mario Mandzukic.

Real Madrid are still the most likely in the competition to regain their European crown, but the form of Barcelona and Lionel Messi will worry the Galacticos.

Last season's La Decima success was a glorious footnote in Madrid's overall history, but with the Champions League holders in differing form, they have a tough task to be winners once more. 

Juventus are the dark horses of the competition, with the likes of Vidal, Paul Pogba and Carlos Tevez always looking impressive.

If the trio can continue with their current form, Italian football might once again find itself at the top of the tree after a sustained absence.
