Arsenal got a good spot I must concur and PSV has always been a worthy competition in getting the team the three points they need. For the preliminary stages, I ain't scared until it gets to when the pressure of premier league and other league matches starts bumping weekend in, weekend out.
What the gunners need is a team that doesn't lack stamina or whose muscles bow to cramps once the game gets above 90minutes.
I think Arsenal will win the group because seeing Arsenal's game in the EPL this season is quite good with 3 wins and 1 draw. For second place, maybe Sevilla, why Sevilla? Even though it is not doing well in the league, in the European arena it cannot be underestimated. PSV is indeed good but in my opinion it will occupy the 3rd and final position, definitely Lens
Based on their performance in the Premier League, Arsenal is the most favored team in Group B. Arsenal performed extraordinary in their last match when they destroyed Manchester United, they managed to break into Manchester United's goal three times which proved that the sharpness of their front line could still be relied on. Comparing the opponents Arsenal face in Group B will give them the opportunity to finish as Group Champions, while the runner up will probably be Sevilla based on their experience on the European stage.
