Is Montpellier for Real?

Montpellier HSC never won Ligue 1.
But they've been doing better and better in the past few seasons. Maybe they can be a contender, finally.

The game against Lyon certainly showed that they can play well in crucial games. They certainly outplayed Lyon, and they more than deserved the resulting scoreline:

tirs = shots; cadres = on target

Clearly, based on the statistics, Montpellier was the team that attacked throughout this derby.

But can Montpellier keep up against PSG, Marseille (who's climbing fast in the standings) and maybe even Lyon?
...Although Lyon clearly is not a great team. They could never score 7 goals in one game, without outside help... (For those who might have a hard time placing this allusion, it hints at the last game Lyon played in the CL in 2011, in Zagreb.)
