The opportunity does exist for Manchester City to add another title in the Champions League this season, but it's still too early to talk about now because we haven't seen how all the teams that entered the Champions League will look like this season. There will definitely be surprises in the Champions League this season and all teams really have to work harder when competing in the Champions League because strong teams are not only in England, but also from other countries this season.
Any team that competes in the Champions League is regarded as the strongest, most capable, and best-performing squad in its respective league. Since being eligible for the Champions League indicates that a team is among the champs in their league, none of them would think less of the other because they can compete and lift the Champions League trophy like the others.
Teams that haven't won the Champions League trophy in a while would like to make another attempt to do so this season, while those that haven't in the past would like to compete for the Champions League title(increasing the level of competition in the Champions League this year). I can't wait to see how Manchester City and the rest would dig out their match result this time around
