The coach is experienced in Champions League as a player in the past and as a coach with Barcelona but he is assigned a big task in PSG. They have some big losses in this summer, Neymar and Messi left, and seems to rely on Mbappe for scoring goals.
Well even without those big players they lost, the new signings are beginning to adapt and they had quite a very good performance so far and look like a team that would do well without them being involved, thank goodness they didn't lose Mbappe as well because currently he's he most outstanding player in the team and a key to them performing better in the Champions League.
Luis Enrique is an excellent coach. He will be at the top of my list of favorite coaches. First he did a great job with Barcelona. Has been able to dominate La Liga and Champions League. He is also experienced enough for the Champions League platform. And that is exactly what PSG need. PSG's long-standing aim is to perform well in the Champions League. But despite spending a lot of money, the team did not perform as well as expected in the Champions League.
Secondly, Luis Enrique has the experience of working with a youth-oriented team like Spain. He strengthened Spain's mediocre team. We have seen some excellent performances from Spain in the last World Cup as well. That's why I think Luis Enrique will be able to strengthen the PSG team as well.
