For me they are the best team and they have the best players. I think they need to fix few things to make the team even better like the midfield. Otherwise, the other teams are searching for players to recruit and to improve their teams too. Manchester United might become a threat along with Arsenal which I expect to be as competitive as the previous season. Liverpool will be on the list once they fix their broken system last season..
Well, Manchester city has done well in this season by embracing many titles because of the potential players their coach brought to the team, and I think their coach will still maintain the players to continue next season so that they will not experience any disappointment in premier league competition next season and other competitions too. I believe, Manchester city will improve higher in the area of the midfield by impacting a new skills to the midfielders so that they will do better in next season, because their fans want to see improvement with the team by maintaining the first position from the beginning till the end of the tournament next season. If Liverpool management can bring in new players in this summer, I think it will make them to improve too because their performance in this season was very poor compared to last season that made them to achieved second position.
