With conditions like now of course manchester city must move quickly in the transfer market, especially last summer they only brought in one player and instead unexpectedly they had to slump after rodry was injured, actually guardiola does not have a habit of shopping for players in the winter because they usually focus more on the summer transfers market. but this season they have to break that habit to improve their current condition, so far, I see that the signing of Marmoush has had a positive impact on their attacking line, but the purchase of Khusanov and Vitor Reis so far has not had a significant impact, while the signing of Nico Gonzalez looks like panic buying after they were slaughtered by Arsenal 5-1.
Any decisions that comes from Guardiola right now in my opinion wouldn't be the best for the team, I think his marital status is still there unless he has someone that has taken the wounded place for him and move on otherwise, this season and next is going to be a long journey for the team. I don't think there is absolutely anything wrong with this team, what they need is just readjusting the existing players and find some defenders a good center back.
There is ongoing discussion for Gonzalez to take place of Rodri since he is no longer active and been on injury but who is going to replace Walker. Who is going to perfectly fit into that role because there seems to be no sign of happiness between Walker and Guardiola be he left for Milan, there is many things that need to be sorted out and resolved before Manchester City can be in a perfect conditions that's why I insisted that as long as Guardiola marital divorce is still on, there is going to be long problem in this club.
In this case I personally will not try to discuss his marital status because it is indeed a personal matter and not our domain to comment on it, because after all as a professional coach of course he will be able to separate between personal matters and his status as a club coach at this time.
So far the recruitment of Nico Gonzalez is one of the alternatives for Guardiola to cover the loss of Rodri, although I think he is a panic recruitment from Guardiola but with his abilities of course he will be able to cover the gap left by Rodri later, while the hole left by Walker is currently often replaced by Akanji and also Nunes, so that indeed the departure of Walker actually does not have a significant impact especially instead Guardiola no longer chose him as the first choice as a right-back this season.
