As Manchester City have been underperforming this season due to a lack of quality midfielders, a quality midfielder will be a key part of Manchester City's plans for the time being. But I have also seen many discussions that many are claiming that Pep Guardiola can leave Manchester City and take charge of another team in the next season.
Pep Guardiola is one of the best managers so if he were to leave Manchester City and go to another club I would say that would be a negative for Manchester City. But if Pep Guardiola plans more seasons with this team instead of leaving Manchester City, then I would say that next season he will change every part of the team and bring good quality players to Manchester City.
This is a big problem that Pep Guardiola must solve because losing a creative midfielder will make their attack line not run well in scoring goals. Pep Guardiola still has a contract left with Man City so he will definitely focus on finishing the job and trying to evaluate the weaknesses they are currently facing. If the management gives him the opportunity to recruit the needed players in the upcoming transfer market then I am sure he will solve the weaknesses faced by Man City at this time.
If he leaves then Man City will certainly face a new challenge with the coach who will handle them and maybe the positive trend that has been built by Pep Guardiola will slowly collapse. The new coach may not necessarily be able to provide what Pep Guardiola has achieved the management must consider many things before making a decision.
