It is clear that Manchester City's season hasn't gone completely to plan this year. After last season seemed to be a walk in the park for the Centurions, Pep Guardiola must look to the summer in order to get back to the same level as before. 

Despite having a game in hand, Manchester City fans are not feeling as comfortable as they were this time last season. Liverpool are proving to be worthy challengers and Guardiola will be well aware that he cannot afford to allow his team to slip up from now until the end of the season.

Having slipped up more than they're used to in the league, the Sky Blues have made life really difficult for themselves.

But what has changed? Have Liverpool just got better? Or is there a deeper frustration within the City camp, leading to some off par performances over the course of this season? A mix of everything really and, while this incarnation of the City side may peak with a stunning quadruple this season, things do need freshening up going forward.

Indeed, Guardiola will be eager to look for some changes during the summer, in order to get back the dominance of last season. Here are a couple.

Find a new Fernandinho 

With one of the league's greatest holding midfielders beginning to show signs that his age may be catching up to him, it may be time for Pep to find someone who can emulate the masterclass that Fernandinho has been providing over the years.

The 33-year-old Brazilian has been in and out of the squad this season with injuries. So, Pep Guardiola must look to the board in the summer and find someone who will bring the same balance that Fernandinho does.

Clear a way for youth

With a number of players beginning to their reach mid-thirties, Pep must begin to look at where he can begin to move and replace around the club.

Phil Foden has become a prime example of the exceptional youth City have hiding in their academy, and with players like David Silva and Vincent Kompany reaching the end of their peak years, it will be no shock to begin seeing names like Philippe Sandler start breaking into the squad.

With the end of Kompany and Silva near, it truly is the end of an era at the Etihad.
