Manchester City need to shake up the squad, they need reinforcements but that can only be done in the summer. Their recent three losses to Real Madrid and now Liverpool yesterday is not good at all. I am sure that Manchester City will make good signings in the summer to improve the squad.
Well, you are right for sure, but you are also making this look or sound like it's now they Manchester city started losing match, aleast I know that since this season began, they've not been in their best form just as they were during last two seasons which saw them going home with the premier league title.
They indeed need a total overhaul of players but this can only be done in the summer in preparation for another season, because even if they can do the overhauling now, it's already too late for them as they may likely not make it to the top anymore.
In this difficult situation, Pep Guardiola certainly hopes the season can pass quickly, so he can enter the transfer market to recruit new players and overhaul the depth of the Manchester City squad. There are more than 10 games to go until the end of the season, and before then, Pep Guardiola must ensure his team can finish in a decent position, namely the Champions League zone. It is no longer realistic to talk about returning to the top of the standings, as Manchester City is already quite far behind in the current race.
There is always something at stake when a team is having a bad season, but I don't see the series of defeats experienced by Manchester City as the end of their glory era. Sometimes setbacks happen slowly, and sometimes they happen so quickly that they seem surprising. Pep Guardiola will certainly fix everything for next season, starting with overhauling the squad depth when the summer transfer market opens.
