"I understand French, but I speak like s**t," said Maxwell, PSG's cosmopolitan Brazilian full-back, when presented to the media for Saturday's pre-match press conference ahead of the Classique at the Stade Vélodrome. "As there are many of us who speak Italian, it's not always easy to talk in French," he added.
That strong Serie A influence inside the PSG dressing room, augmented by then-coach Carlo Ancelotti and sporting director Leonardo, was thought to be at the root of the team's ills in the early months of last season, a problem put right by - ironically - a night out on the pasta and pizza.
Even if they still fall short of Blanc's stated wish to have French as the unique language of the dressing room, it seems the squad this season has overcome its communication problems, and - perhaps it should only be whispered quietly - actually look like a team.
So often under Ancelotti, individual acts of brilliance provided the solution when team play was found wanting. That too had been much the case under Blanc so far, but the come-from-behind win at the Vélodrome showed a solidarity, a willingness to all pull in the same direction, that had been conspicuous by its absence under his predecessor.
"At the Vélodrome, their maturity caught the eye. Their attitude too," wrote L'Equipe on Monday, referring in particular to PSG's reaction to the first-half, unjust dismissal of Thiago Motta and the subsequent penalty scored by André Ayew. "We showed character," stated talismanic defender-cum-cheerleader Zoumana Camara, while teenage midfielder Adrien Rabiot praised the team's "attitude that shone through".
That attitude was a blend of the belief that even down a man and a goal after barely half-an-hour they could triumph at the home of the team that pushed them hardest last season, as well as a readiness for self-sacrifice by some of the game's most high-profile individuals.
The most flagrant example was Edinson Cavani, who - as a €64 (£54m) million summer signing - might have been expected to have all the self-awareness and humility of an opera diva.
The Uruguayan, in a similar fashion to fellow recent Ligue 1 import Radamel Falcao, has none of the airs and graces of such prima donnas, however, and though he did not score, his work-rate ensured Motta's absence was not felt too keenly.
That was partly down to Blanc himself, who - to a degree - forced Cavani into a thankless, workhorse-style role with the removal of Ezequiel Lavezzi and his replacement by Rabiot to ensure PSG maintained a three-man midfield. It even led L'Equipe to quip PSG should consider playing with 10 against 11 every week as it appeared to provide the solution to the thorny issue of how to play both Cavani and Ibrahimovic in central attacking roles.
Perhaps it is overstating the case to say that all PSG's ills have been remedied. They were on hostile territory, and so with their backs pushed still harder to the wall, players of their ilk were always likely to respond. If they hadn't responded in that situation, would they ever?
Also, they knew that Monaco, their most likely title rivals, had gone to the Stade Vélodrome, also gone behind and had won earlier in the season. Claudio Ranieri's men had also triumphed 24 hours earlier against Saint-Etienne to open up a three-point gap that PSG knew they could barely afford not to close, even at this early stage of the season.
Whether they can produce a similar display after the international break against Bastia in their next home game will perhaps give a better indication of whether the ésprit d'equipe they showed on the south coast is here to stay. Under Ancelotti too, the squad tended to perform in big games. But triumphs such as those in the Classique have a way of bonding sides together, so perhaps Paris' restaurateurs may not get a big night from Blanc's boys this season.
