Manchester City are more interested in Champions League but they don't sacrifice Premier League. If they can not win Premier League, it can be because another competitor have too good performance in this season to beat Manchester City.
I don't think with Manchester City sacrifice with Primer League and most priority Champion League in this season because both trophy most important have to get, I know with Manchester City trouble never reach for getting Champion League trophy after several season.
Pep hasn't won the premier league three times in a row and that'll be a record he'll love to have with his dominate Manchester city team. Last time Pep tried wining, Liverpool spoil that record. Only Manchester united has won both three times and four premier league title in a row. If Pep Manchester city wants to go down in record as one of the dominate side in the premier league then they have to be ready to break this record that Manchester united kept years back.
Pep has his eyes on the premier league title as well as the champions league and he'll love to win them both with other trophys. Can Pep Manchester city team win both tournament, the answer is yes as Pep has an indepth team squad that players on the Manchester city bench are guaranteed starters if they weren't playing for Manchester city.
