#2 Paris Saint-Germain
Perhaps the safest option on this list is the Parisian giant, Paris Saint-Germain. Much like how Pep Guardiola played it with Bayern Munich, Luis Enrique can step into Paris knowing very well half his work is already done.
A Ligue 1 title shouldn't be too tough for him but the challenge lies in the UEFA Champions League and he has the kind of experience of dealing with teams who've won the competition before. He did with FC Barcelona and could very well guide the Qatari-owned Paris Saint-Germain to their first ever European platinum triumph.
With the kind of squad already at his disposal, it seems likely that should he be offered the job, he can succeed without too much of a problem. They have the best forward line and midfield in the whole of France and he can concentrate on their efforts in Europe.
