A team can win the champions league without winning their domestic leagues, Liverpool has done this before and Real Madrid the biggest winners of the championship league have lost their domestic league but won the champions league many times. Arsenal are capable of winning the champions league if they are determined and have a good squad depth. Arsenal always start their season very well but they start having issues when the season has gone half as they don't have quality players on the bench that they can use when their starting eleven isn't giving the coach the results he wants. Instead of trying to sign starting players that'll be very expensive, arsenal should hurt for backups.
We know that player rotation is very important to maintain player fitness, especially if you are pursuing targets in the domestic league and UCL league. In fact, in the last two years under coach Arteta there have been many developments and changes, in the domestic league they competed very closely with Man City and last season in the UCL league they also played well, but many Arsenal players were tired. in the end they were no longer consistent in the end. season. This was also proven when they lost to Bayern Munich, in fact their game was quite good but they did not have reserve players who were the difference who could score goals in every match.
This is Arteta's main task next season, strengthening reserve players so that it is not impossible to be successful in UCL matches. It is true that they are not favored to win the UCL trophy next season, but in football anything can happen and luck definitely exists in football.
