I think Lens already knew that this would be a game they would lose, that's not really a shocking result. However, to get back to that second place is definitely a hard thing to do, they didn't calculated that they would win against PSG, nobody really "expects" that, if it happens (which it does sometimes) then it is great but you do not put that in there, you just assume that you would lose.
So Lens must be thinking about some other games, both for them and for their competition as well, and think maybe they could get it somehow. I personally hope that it would be a close one, everyone should be fighting hard for every spot so that it would be good to watch, I do have a lot more fun that way because it really does provide a great entertainment.
