"I think we're going to have to win them all - we're capable of doing that but it's going to take an enormous amount of concentration in every game". You had seen what competitive football was about.
"But hopefully that win will give us more confidence". Mathematically it is still possible now, even if it is hard, but we will give it a go.
The Frenchman's experiment proved to be a success as goals from Alexis Sanchez and Mesut Ozil helped Arsenal end a run of four consecutive away defeats.
"The first time in 20 years", he said of the formation switch.
"Yes, I did something I had not done in 20 years - but that just goes to show that even at my age I can still change", he smiled. Against Palace and West Brom, we had 70 per cent of the possession and we lost.
While Arsenal are seven points behind fourth-placed Manchester City, they do have a game in hand and will be looking to make a push for the last slot for next season's Champions League.

"Dani has done everything right, but the ball has got right down the line of Petr Cech".
Boro performed creditably, but find themselves still six points adrift of safety with just six games remaining, and knowing time is running out fast.
Manager Wenger indicated the new system had given the players fresh belief but said it was not necessarily going to be a model for the future. Even then, Manchester City could afford to drop four points from its final six games, with a goal difference now superior to Arsenal's.
"The players were awesome in terms of their effort and commitment and attitude towards the game".
"The players were incredible, I couldn't ask any more of them", he said.
