If Manchester City, Real Madrid and Bayern Munich are the top three clubs in the Champions League, then I think one more club should be added here and that is Arsenal. Maybe we don't see such a good performance from Arsenal in the Champions League, that's why we can't put this team in the list of favorite teams.
If you add Arsenal to the list, you will have to consider to add more clubs to it. Arsenal is good but not like a very strong team with too much better competitiveness than many clubs around Europe. Arsenal are not much better than Barcelona and if you bring this question up for discussion, there will not come to any universal conclusion. It means these clubs are not different too much in quality and competitiveness.
I have included Arsenal in the list of best teams because Arsenal are ahead when compared to other teams. Arsenal competes hard with Manchester City in the Premier League but they have consistently underperformed in the Champions League but we have seen this for a long time. While the big teams plan to win the Champions League, their destination seems to be to win the Premier League. But if they plan the right players for the Champions League with the players they have in the club then they will definitely do well in the Champions League.

Injury problems are unwelcome and can happen to every club, but Arsenal's players are known to have the most injuries every season.
Injury issue was most commonly in era of Arsene Wenger and several previous years. It seems that in last two seasons, injury is no longer biggest problem in Arsenal and it helps them to play impressive in Premier League and Champions League.
Arsenal didn't have too many injury problems last season which is why they lost the Premier League title with Manchester City on points. First of all, every important player should try to finish the whole season without injury because while other teams have good quality backup players, but Arsenal do not have good quality players as backup, it is definitely a big problem for them.
