I see that Arsenal is solving this problem, now it seems that Arsenal is making several transfers that allow for an equal quality between the main and reserve players so that if there is a player rotation it will not have a significant effect on the team's performance.
I think it's very likely that Arsenal will do well in the Champions League next season, the quality of this team is increasing now and they deserve to be reckoned with.
Arsenal really shouldn't be underestimated next season, especially in the Champions League because Arsenal themselves are also very aware that they still have to improve on existing deficiencies to be able to wade through an even greater next season. And not only in the Champions League, Arsenal must be taken into account, but also in the Premier League must also be considered from the start of the season, because Arsenal will try to be consistent from the start of the season to fight for the title next season.
It'll be huge disadvantage to any club that'll underestimate a club like Arsenal come next season because Arsenal might end up giving such club a thrashing of their life
Mikel Arteta has done exceptionally well in building the Arsenal team to a very strong side and as it stands, I think Arsenal is capable of beating any European club.
Coming so close to winning the English Premier League last season is enough reason for any European side that's facing Arsenal in the UEFA Champions League competition next season to be very careful and strategic against the North London club or face unwanted humiliation
