The next season champion league tournament will be a very tough one then this season due how so many clubs are prepare for the next coming season, apart from the Manchester city there so much teams that are are going to be tough as you mentioned them earlier expecially, a team like arsenal I'm expecting a good outcome from them. Because since there able to win the champion league this season; they want dominate the entire next coming season, and in my view arsenal can make that happen with how they improve their performance better, But nevertheless let us be wait and see what can actually happen in UEFA Champions league we can't make an early predict.
I love it when clubs become very competitive the more it shows that they are actually fulfilling what they are been paid for, because a lot of clubs are trying their best spending money on players and they are not getting results and instead of selling the player they will rather sack the coach sometimes i feel the players are more valuable than even the coach they don't sack players the highest they can do is to sell players but the moment the management is not getting results from the club the next thing they will do is to sack the coach and the club that have falling victim of sacking coaches is Chelsea i hope when they get a new coach they will get what they want. Manchester city are always prepared and will do what is best for them, arsenal will not go anywhere they might cross the group stage but their is nothing longer for them. it will take arsenal a longer period to get to a convincing point that they will win the champions league. before you know it the champions league have started and this will be the best champions league to have experienced just watch and see because i even feel this battle is going to be between real Madrid and Manchester city this time around.
