The total number of rounds for the Champions League小组赛 is 6.
In order to determine the current scenario, let's take a closer look at the fixtures and standings of the 2018 UEFA Champions League:
In the second leg of the group stage in the 2018 season, the heavy favorite to win the European Super League was Paris Saint-Germain, a club that has been thriving in France's top tier football league. As per the current form, they have been enjoying unprecedented success, leading the way with ten consecutive wins in the French league.
After defeating Napoli 1-0 in their opening Group Stage game against Napoli, PSG suffered another setback when Lionel Messi and Kylian Mbappe failed to find the back of the net in their next match, allowing the surprising result to hand over to Roma for the draw. In the absence of these attacking duo, PSG struggled to find any significant offensive flair, which resulted in anemic performances on both the domestic and European stages.
The weak spots of PSG were also starkly apparent as the team struggled to generate effective counter-attacks, with their lone pairing of Lionel Messi and Kylian Mbappe lacking cohesion and linkages within the attacking unit. Their defensive displays exhibited a lackluster level of tactical acumen, leaving their opponents to exploit various vulnerabilities.
"Paris Saint-Germain's stunning display last weekend, with Lionel Messi and Kylian Mbappe failing to deliver crucial goals, has left many fans and experts questioning the strength of their collective attack prowess. The team appears to be struggling to establish a cohesive structure for their attacking lineup, with each one unable to function effectively as a part of a well-coordinated offensive strategy," said renowned football *** yst Richard Godfrey.
"The worrying aspect of PSG's performance lies not only in their inability to score key goals but also in their defense, which has demonstrated a concerning lack of tactical finesse. As an entire team, they must address these weaknesses if they hope to improve their chances of progressing through the tournament and secure a spot in the knockout phase of the Champions League, where they'll face some formidable opponents such as Barcelona, Liverpool, and Real Madrid," added another commentator.
While PSG's current campaign may appear promising due to the presence of top talent such as Lionel Messi and Kylian Mbappe, it is essential to note that if they fail to adapt and address these flaws quickly, it will undoubtedly become a laughingstock in the world of professional football, further tarnishing their reputation as one of the world's greatest teams.
