Mourinho brings memories and more controversy back to Rome in Champions League visit

1. Paris Saint-Germain are the clear leaders in the current Champions League power rankings, with their 6-1 victory over Slovan Bratislava demonstrating their continued dominance. Their upcoming matches against Manchester City and Barcelona are particularly significant, as they prepare to compete for the title.

2. Arsenal, the runners-up from last season, are determined to go one better this year. Their recent form, led by Martin Odegaard's excellent start to the season, is highly promising. Their squad depth and attacking capabilities give them a strong chance of finishing in one of the top two spots in their group.

3. Barcelona emerged as arguably the most in-form side after a stunning start to the season, scoring 22 goals in their first five games. Despite not replacing Robert Lewandowski, their attacking form with players like Raphinha and Lamine Yamal, along with Rodri's addition, has sparked into life. They face tough tests ahead, but if they continue their strong away performances, they could rise to the top of the rankings.

4. Bayern Munich's dominance in the Bundesliga and their impressive start to the Champions League, including a 5-0 win over Bodo/Glimt, suggest they remain a top contender. Harry Kane's goal-scoring prowess and Michael Olise's emergence could propel them to the top of the standings. Their experience and muscle in midfield, particularly with Rodri, will be crucial as they vie for the title.

5. Manchester City, despite the changes and challenges of the summer, still have a strong claim to being title contenders. Their domestic form, including a 2-0 victory over Porto, indicates they are still a formidable force, even with Guardiola's underwhelming record in the Champions League. A positive result against a side like Barcelona would be a significant statement of intent.

6. Real Madrid, returning under Jose Mourinho, are facing the pressure of avoiding a repeat of last season's trophyless season. Their 2-1 victory over Inter Milan shows they are competitive, but the road ahead is long and challenging. They will need to perform at their very best to climb the rankings and reach the pinnacle of European football.
