"It is a big comfort for us, first of all to give the players a breather," the Frenchman told arsenal.com. "Yesterday they could stay with their families and they are not under mental pressure.
"Sometimes, [it is difficult] to focus when the time is a bit short. We have four days. It's interesting for all the clubs. I think it's a big improvement for us.
"Even the little knocks, you have a chance to get the players back and fit for the next game."
