PSV are in Group B and we can all see the form of performance shown by each of them in their domestic league at the start of this season. Of the four teams there, I think there are only two teams that are really strong at the moment, namely Arsenal and PSV because the other two teams are still quite bad in their respective domestic leagues so there is a possibility for PSV to qualify for the next round in Champions League although maybe PSV will not be ranked first in group B.
Group B has a much more balanced representation of team strength and in my opinion it will be difficult for this group to see who advances to the next round because almost all four representatives have almost the same quality. Arsenal has a slight advantage after seeing their performance in the Premier League and in my opinion, of the four teams Arsenal has a much greater chance of qualifying for the next round. The rest depends on how PSV, Sevilla and Lens perform because if you look at the performance in their respective leagues it will be quite difficult to determine who will qualify.
The Champions League results cannot only be seen in the domestic league because there are big differences when they play and here also determines mentality and experience. My prediction is that PSV or Sevilla will most likely qualify with Arsenal, Sevilla has a good mentality when playing at qualifying level and is very different when playing in the domestic league like when they won the European league last season but that's just my prediction.
