However we must have all seen how ambitious they were against Sevilla in Emirates the last time. I'm expecting to see the same ambition here as well. In addition to that winning this game means they are securing the lead at the same time. Therefore I don't expect a big mistake from Arsenal.
Looking at the situation, the depth of performance of the Arsenal players at the moment seems to look better than last season, while Lens has had an inconsistent performance and this away match will definitely make it difficult for Lens to beat Arsenal and even being able to hold a draw is like luck.
I would say Arsenal team was unlucky so they lost 2-1 against Lens. Arsenal's performance was not weak in this match. They performed very well. But Lens scored full points in the home match.
However it was a disaster for Arsenal. And in the next two matches, Arsenal performed very well and won. Arsenal will play at home against Lens in the next match. However, Arsenal are a bit off form right now. Even so, my guess is that they will dominate the home match against Lens. The Lens team cannot be called strong. Lens team is quite weak compared to Arsenal. Arsenal will avenge their previous defeat in this match.
