Barcelona and their Champions League exploits are by now a well-known love story.

The Catalans have been chasing the coveted cup for years now, failing in extraordinary fashion ever since the 2014/15 season when they clinched the trophy for the last time.

First came Juventus, who smashed the Catalans in Turin, then Roma at the Stadio Olimpico and finally Liverpool at Anfield and every single time they were outclassed, outgunned and quite frankly - embarrassed.

Needless to say, the whole team constantly underperformed and while it's difficult to point towards a single player for those disasters, Luis Suarez comes really close to taking the prize by himself.

After all, the Uruguayan has been sub-par for quite a while now and interestingly enough, his last away goal for the club in the Champions League was four years ago as he failed to rattle the net in the last 19 games.

To be more precise, since his last successful strike, he attempted 59 shots and none have ended up beating the opposition goalkeeper.

Of course, with Suarez disappearing in crucial games on the road, it isn't a surprise that Barcelona were largely outgunned when it mattered most.

Not to mention that a similar thing happened just the other night when the Catalans travelled away to Slavia Prague and just barely got away with a narrow 2-1 victory.

Despite having five shots on the night, Suarez was nowhere near his best, failing to make simple passes work and losing possession. As a direct result of that he tallied a disappointing 64% passing accuracy, one big chance missed and lost possession 15 times.

Of course, he has been quite effective in the domestic league, tallying five goals already in La Liga, but those goals just paper over the cracks that are starting to show repeatedly.

The occasional wonder goal shouldn't be enough for the 32-year-old to be constantly picked and Valverde's blind trust in the Uruguayan will sooner or later catch up with him once again.

His performance against Slavia Prague was nowhere near an isolated case as we've seen a similar thing happen against Borussia Dortmund in Europe or even against Granada and Villarreal in La Liga, just to name a few.

This is slowly but surely turning into a horrible trend for the Uruguayan and the time has finally come for Valverde to make a bold decision and drop the star who's clearly past his prime.

Let's see if he musters the courage to do so.
