After winning their first Champions League title with Luis Enrique, PSG management may not want to let him go easily. Even after winning their first UCL title, they may not have made a mistake in paying tribute to Enrique. Enrique has not yet been able to fully organize his team, he may need some more time to bring the team to consistent performance. I would expect 2-3 more seasons to be consistent in the Champions League. We may see Enrique's poor performance in a few days, because his team is already becoming a threat to other teams.
We just have to wait to see how things turns out for him. Just because the team is facing threats from other teams doesn’t mean they can be defeated by them so easily. If they manage their play very well, they can still outshine their opponents and still become very undefeated amongst their peers. Luis Enrique knows what is on check for him after winning the champions league last season, so I don’t see him relenting on important issues like this. He needs to keep his job and his prestige for how far he has come, so he won’t easily give in no matter the pressure from the opponents, he’ll try his best to remain the best even though it is not easy to achieve by any manager.
