I think every team in the Champions League needs to follow Manchester City. Teams should think about what kind of tactics Man City is applying. I hope the rest of the teams will perform well this season. I want the Premier League to become more competitive.
Last season the Premier League also looked more competitive in my opinion, because Manchester City was really consistent in chasing Arsenal points last season. And it is likely that next season Manchester City will still be very strong even though other teams are also making better changes so they can make it difficult for Manchester City. But if other teams follow the tactics developed by Manchester City, it will actually make the other team weaker because it will be easier for Manchester City to find the key when making their attacks.
