For my part this is actually quite easy. Overall, i think there is a little lack of humility and respect surrounding this team, especially embodied by N'gapeth, which would leave me with a little hidden smile once they fail.
For pure volleyball reasons they have my highest respect for their exciting display of volleyball. There is no doubt about it. But still, i can't help myself from wishing their counterparts "good luck"......
At the end this is subjective so It's absolutely normal not to love them, but I wanna say that what you read as lack of humility I read as 'having fun of court with my teammates', and that to me it's really connected with their exciting volleyball: they won't be so exciting if they wouldn't have so much fun being and playing together...
As I said everyone has is own impression, I don't want to convince you but just to explain my point of view
And consider that our French 'cousins' are kinda our rivals in every sport (probably because of soccer), so I should hate them actually
Ah, when a journalist asked Piano what N'gapeth said him under the net during the matches, he answered kinda laughing "everything! How patient I had to be!"
