Mathieu being absent from Strasbourg team last week-end was presented as the key of Quimperlé's qualification and Strasbourg's elimination.
Well, I wouldn't subcribe to that explanation. PHM signed for four matches so he was going to miss one tie no matter what; Quimperlé being the weakest team on paper prior to the start of the competition, it made sense to schedule Mathieu for the other ties. The key result for Quimperlé's qualification was IMO their tied score against TC Paris. Had Simon and Paire not blown up their respective very winnable match against Quimperlé, Strasbourg would have qualified even after losing to Quimperlé like they did.
