If I'm remembering correctly, Luis Enrique won his first and only Champions League as a coach whenn he managed Barcelona and these players mentioned where all in the Club.
So give me reasons why Luis Enrique won't make that up once again. PSG do not have a deadly squad no more, they might even be a weaker team to Manchester United, yest Manchester United are complete dicks.
Lionel Messi benefited from french as more of them wanted him to win the Ballon d'or since he moved to PSG that same season. Kylian had his egos and pride up, Lionel Messi achieved lots at his age, I expected him to be humble. When he moves outside of Pari we will know if he can work hard to win the Ballon d'or.
The problem isn't Luis Enrique per se or the players he has or has not coached, the problem is that Barcelona was on full steam back at the time because they were pretty much in their prime and they had a competitive league and the rivalry with Real Madrid that always kept them going harder and better. PSG is a lone wolf in Ligue 1 and they have all these average opponents and then suddenly they face teams like Manchester City. For PSG the gap in required performance between the competitions is huge and that can be a disadvantage when they are required to deliver.
