There is no doubt that Lens will be able to win this match easily. In my opinion, their opponent is not going to pose too many problems for them, as I do not think that will be the case. Strasbourg is currently ranked at the bottom of the table. Their play isn't encouraging at all, and they aren't doing very well. I think Lens should have an easy time securing three points in this game.
in the last few matches that Lens has had, they have been almost unbeatable and they even beat PSG with a score of 3-1 last week. next Lens will face Strasbourg and like you, I also predict that Lens will win smoothly at this match.
They have been doing great that's true but I think it's temporary. They are normally not good enough to beat the whole league, they are not there yet, maybe they could build a team that could do that in the future but for the time being they are not there yet.
I believe that they had a good streak and a good period but they will start to lose points soon enough, maybe not on strassbourg game, maybe they will win that too but soon enough they will start to lose to teams they were expected to win, which will be a problem for them. I will never doubt PSG winning the league title, I know it happened once, but I think it will not happen again for a long time.
