I support The Gunners, I don't expect anything too much from the Arsenal squad. although at this time Arteta has deepened his squad by bringing in several newcomers, the fact is that we cannot measure for sure, at the time when Arsenal played match after match in the Champions League.
I am more realistic, Arsenal have been absent for quite a long time in this competition. at least, the team's mentality and readiness will be greatly tested. and Arteta is well aware that in this competition there are many strong competitors. then, will they be able to do it, even if they qualify for the next phases and for sure we will never know before this competition starts.
but if we talk based on statistics and theoretically, Arsenal should be better prepared with a more competitive squad to face competition in this competition. anyway, as a fan, i will still support them.
Speaking of United, this team is not my favorite team. but I like the style of coaching Ten Hag. Even though United have struggled in recruiting players in this summer's transfer window, I'm sure Ten Hag will do his job as best he can and bring the best to his squad. so, let's just enjoy when this competition has been held.
