I think so too, the reason is PSG squad can't be said to be perfect now, their chemistry not really good. Also, they are still having difficulty against team from Premier League (Newcastle). So yeah the chance of getting the Champions League Trophy is not that big, but there is still time for Enrique if PSG can qualify tonight.
Luis Enrique had this team in the Champions League final against Juventus Turin in 2014/15:
Marc-André ter Stegen – Dani Alves, Gerard Piqué, Javier Mascherano, Jordi Alba – Ivan Rakitić (90.+1' Jérémy Mathieu), Sergio Busquets, Andrés Iniesta (78. Xavi) – Lionel Messi, Luis Suárez (90.+6' Pedro), Neymar
I think this is enough proof to know that Enrique was a lucky guy, a lucky coach in the right place at the right time. I won't say that Enrique is bad or is not experienced enough, but I think he lacks intensity as a coach to support his team when they have some weaker times. I prefer coaches like Klopp or Guardiola who can lift their team up with all their passion and intense coaching. Enrique isn't that way.
I suppose you might be wrong when you talk about Luis Enrique when he was working in Barcelona, we know Luis Enrique is a gear coach and he had good performance when he was working in Barcelona but this coach is now working in a different team than Barcelona in which Luis Enrique is having a different situation and we can't expect to see the same performance from Luis Enrique and PSG in the Champions League, in fact, everything is changed and predicting PSG for the this Champions League is not that easy.
