Luis Enrique Facing Acid Test as Barcelona Boss in Champions League vs. PSG

Luis Enrique and Barcelona have been enjoying themselves so far this season, but their first real test comes in the form of their trip to Paris to face PSG.

The league's opening fixtures have been kind to Enrique, with the toughest two games being their home match with Athletic Club and away clash with Villarreal.

But really, no games at the Camp Nou will prove too difficult for Barcelona other than when Real Madrid come calling, or they get deep into the Champions League.

That has been reflected in their current clean-sheet record.

In the opening seven games of the season they have not let in a single goal, either in La Liga or against Apoel Nicosia in the Champions League.

So traveling to Parc des Princes will be the toughest moment of Enrique's tenure so far.

The fact that Barcelona haven't conceded isn't just down to their easy fixture list, because saying that would take credit away from the good performances of Jeremy Mathieu and Javier Mascherano.

But Claudio Bravo hasn't had to work too hard from being 20 minutes away from breaking a club record for longest start to the season without conceding.

Per SPORT, he is only 20 minutes away from usurping Pello Artola's Liga achievement.

Even if he plays and lets in a goal against PSG, he can still hit that target, against Rayo Vallecano next weekend.

But the trip to France to face Laurent Blanc's men will not be easy.

However it's not as hard as it should be either, which, bizarrely, Enrique might not be happy with.

The French giants are in poor form, with disappointing draws against Stade Reims, Evian, Rennes, Ajax, Lyon and Toulouse so far this season.

The only time it seems like they have hit their stride was the 5-0 home triumph against AS Saint-Etienne.

Furthermore, they also face rivals Monaco after the Barcelona clash, although the Champions League game on Tuesday will be their main focus.

Several key players have suffered injuries recently, with Zlatan Ibrahimovic racing against time to get fit enough to face his former club on Tuesday night.

The Swedish marksman missed the game against Toulouse this weekend and is touch-and-go to make the Barcelona fixture, per Blanc in SPORT.

On top of that, Ezequiel Lavezzi and Thiago Silva have also spent time on the sidelines recently, meaning that PSG will be below full strength.

Enrique, with a Clasico clash against Real Madrid coming up in less than a month at the Santiago Bernabeu, may actually have been hoping to test his charges against a Paris side in their pomp.

However, he won't be complaining too much, because PSG still feature many good players and will give Barcelona their stiffest opposition so far.

While Villarreal were stubborn at the back and needed to be broken down, they didn't look like scoring themselves much.

PSG, on the other hand, even without Ibrahimovic should still ask questions of Barcelona's defence.

So far, most of the defending Barcelona have done is against breakaway attacks, where Mathieu's pace and Mascherano's positioning have been utilised a lot.

PSG might manage to sustain periods of pressure, which will give Barcelona different problems to solve.

In Blaise Matuidi, Javier Pastore and Edinson Cavani, Enrique's Barca side face their three most talented players so far.

If that trio are in good form, then Enrique will learn a lot more about his side.
