Arsenal are playing with a home advantage and are the bookies favourite to win the match, though alot of people feel they might find it tough winning PSV due to the current injury crisis they're facing in their defense line, i think Arteta has to be very tactical in that match because he's not playing against against a small Premier league team he'll give chances.
PSV is one of the biggest team in the Eredivisie League and they've been consistent in qualifying for the Champions League over the years, also are doing very well in their league too, last season they finished second and are currently second in the league this season with 9 points, winning all their matches so far therefore they shouldn't be underestimated because they're capable of facing Arsenal and could suprisingly defeat them if Arteta doesn't strategies properly.
On paper, Arsenal are very favorites in this first leg. Moreover, Arsenal will be playing at home, of course that will be a positive value for them when the first leg starts. I'm sure Arteta is ready enough with the existing strengths and they will even try hard to put strong pressure on PSV in the first leg. I'm sure PSV will find it difficult to provide competition for Arsenal because Arsenal played quite impressively at home like when they beat Manchester United.
However, for PSV they had a sweet record last season when PSV beat Arsenal in the European league. Of course, this will give them confidence to provide stronger resistance. However, betting on Arsenal to win is still our favorite in this match.
In my opinion, the match in the Champions League will be difficult to predict even though Arsenal are the favorites, but their opponents will be able to provide strong resistance in the match. Because every team will play better in the Champions League compared to their game in the domestic league. Moreover, Arsenal have been absent from the Champions League for a long time so they need to play more carefully to be able to secure 3 points in the first match in the Champions League. The first leg match will still take place in about 10 days so all teams still have time to prepare their energy.
I am more interested in the matches in Group F compared to other groups. Where Ac Milan will meet Newcastle United in the first match of the group phase. I'm sure AC Milan had a good record in the previous season because they could easily advance to the round of 16. So they will be ready to beat Newcastle united at sansiro stadium.
