As their rollercoaster of a season continued this week, Barcelona were once again humiliated on European football's premier stage as a humiliating 5-2 aggregate defeat against PSG saw them crash out of the Champions League round of 16.
Blaugrana captain Lionel Messi instilled a small glimmer of hope with a thunderous strike from 25-yards but later saw his penalty saved by Keylor Navas as the two sides played out a 1-1 draw, with the previous catalonian calamity in the first-leg eliminating them in the French capital.
Moving away from the fixture in France, an important month of football awaits Barcelona if they are to prevent a second consecutive trophyless season; it includes a handful of tough fixtures in the La Liga title race and a Copa Del Rey final clash with Real Sociedad.
Providing Koeman's side a golden opportunity to restore the belief is a league tie against rock-bottom Huesca at the Nou Camp on Monday.
With just 20 points from 27 games this season, Los Azulgranas are fighting for their lives, and their misery is likely to continue further in Barcelona.

Despite the omission of their iconic 'MSN' strike partnership, Luis Enrique's side seemed completely unphased as the tricky Spanish winger scored three in quick succession alongside compatriots Sergi Roberto and Andres Iniesta who pitched in with a goal each.
Adriano, Ramirez and a debut goal from Adama Traore added insult to injury in the second-half whilst the visitors pulled back a novelty consolation goal as the tie astoundingly finished 8-1.

Barcelona 8-2 Huesca
September 2, 2018
In a ten-goal spectacle in Catalonia, four goal contributions from Lionel Messi helped Barcelona come back from a goal down to decimate the hopeless Huescans and remain top of the table at the start of the 2017/18 La Liga season.
After Watford loanee Cucho Fernandez put the visitors ahead, Blaugrana responded emphatically and - despite a second Huesca goal from Gallar Fulguera - held on to a 3-2 lead at half-time thanks to goals from Messi and Suarez, who scored either side of an unfortunate own-goal by Jorge Pulido.
The second-half told an entirely different and much more one-sided tale as the Nou Camp outfit scored five more goals - scoring a total of eight past Los Azulgranas for the second time in just over four years.
It took the hosts just three minutes to find the net after the restart. Ousmane Dembele added a fourth with a powerful left-footed strike across Werner into the bottom-right corner, as two assists from Lionel Messi provided goals for Rakitic and Alba with the Argentine completing his brace inbetween.
Messi passed up a chance for a hat-trick for the clubs eighth and final goal, opting to award the spotkick to strike partner Luis Suarez, who matched the illustrious number-ten with a brace of his own, sending the keeper the wrong way.
