Pep will certainly strive to bring Manchester City back to the title next season. If City fails again, Pep's reputation will suffer somewhat. Manchester City does appear to have made quite thorough preparations in the current transfer market. However, I still think De Bruyne's departure is quite unfortunate. I don't think the player brought in to replace him will necessarily be on par with De Bruyne. So, Manchester City could start to lose their strength in one area. But I think my concerns are overblown. Pep certainly knows what he's building at the club.
I think the expectations matter a lot what we expect from someone or what we get in the end that decides about your mood and reviews. The expectations from Manchester city are highly raised as it's the thought of too many people that Manchester city will win the season and make records. It's true that their performance last season was quite impressive and maybe this thing is pushing the people to think like they will win in this season. But with expectations the scenario of the desired team should be matched. As some one quoted in the discussion that the departure of De Bruyne is ultimately a bad luck or unfortunate for the team. So, i think the club should make the decision which meets the expectations.
