"We have shown we can fight and be united, that we can respond to adversity and they are the positives of the day," the club's official website quotes the Frenchman as saying. "The frustration we have is that we did not get the result we wanted, but overall the performance was there from the first minute to the last, and our attitude was absolutely spot on.
"We have gone through an absolute nightmare, a storm, this week. The critics come very quick and very hard, the only way we can deal with it is to respond in the next game, and that is what we did.
"It has been very bad, but as well very positive because it is always an opportunity to show you have some mental strength, so I am very proud of my players because they have shown that."
