Nothing will stop Manchester city from winning their last game in the champions League against Club Brugge. Pep Guardiola already knew that his team hasn't been in their best form, he had to make sure they were not in a bad position in the league. He knows that the champions League new format has given teams more opportunities to qualify even if they had to lose some matches.
The team wasn't too strong and there is no way you are going to be that competitive in all the competition you are participating. You have to prioritise the one that's more intense and go easy on the one that's more flexible. The premier League is more complex than the champions League. Once it's the knockout stages you will see that Manchester city will be strong in the champions League. They won't be losing that much anymore.
It is not yet certain whether Manchester City will win the UEFA Champions League match against the club Broog. Manchester City has reached a level that they are now doing bad performances against the weak parties. The players in this team do not have the confidence to perform well. They have been defeated very badly to PSG. So at the moment it can be said that they may be defeated against the club Brooges just if they are not able to perform properly. Club Brugge are already in a strong position in the points table, they are performing more consistently than Manchester City at the moment so they will go into the match as favourites.
