His star has dimmed considerably, but a lot of that is definitely due, as mentioned, to the PR nightmare at the World Cup. The blunt reality is, unless you play in La Liga or the Premiership (the two best leagues by miles), you are outside the top bracket of football for a huge chunk of your yearly football. If PSG had won a couple of CLs with him leading the way, he may have put himself in there with Messi and Ronaldo, but they kept performing the past few years in the better league. He moved to a smaller club in a much poorer league purely for money, when he SHOULD be playing for either Barca, Madrid, one of the top 4 Premiership teams. Perhaps at a massive stretch, Bayern. Possibly. Only due to the fact I'd think they were considerably more likely to win the CL than PSG.
Hell, for all the "collecting medals" chat, he wasn't in any of the French cup final squads PSG have won because of his injuries, so he doesn't even get that miserly credit. Given that his drive was to be the best in the world, according to many sources, he needs to either lift PSG to some impossible CL dominating height, or he needs to carry Brazil to several trophies, or most likely, he needs to move to a big Spanish or English team whilst he is still young enough and fit enough to do so.
