Manchester City is definitely back, they are getting great results, this easy win for them is not just three points but it is also a way to feel better and more welcome as well. They will have great morale and confidence after this game, so winning could become a lot better for them, which could even help them with the PSG game as well.
This isn't a simple thing, but we need to realize that it is not going to be all that much of a big trouble at all. They are six points away from second place, which isn't that bad for City, if they can keep this momentum going then we could see them end up getting there. I do not think anyone is taking this season away from Liverpool, but at the very least City could fight for a second place.
