The truth is that once Manchester City get their form back, it is possible they will focus on both the Champions League and their domestic league. However, if Guardiola notices that they are still in average form, he will definitely prefer to focus more on the Premier League so they can finish in a better position in the league table, ensuring Manchester City qualify for next season's Champions League.
Now the question arises, when will they return to their best form?
Currently City are like toothless lions who are having difficulty beating their opponents, they were not even able to beat Everton, let alone when facing a stronger team in the UCL. If Guardiola is able to improve his squad after taking advantage of the January transfer window, he must focus more on the domestic league to be able to compete again in the top four. I'm not sure City can survive much longer in the UCL, they will definitely lose when facing the favorites.
I have been thinking back and forth about Manchester City and I was so convinced that they need this one game where they turn it around last second, celebrate a great victory and regain their confidence. But when you watch their games, you can see that there are systematic problems within the team as they can't find the gaps anymore with their game that consists of a lot of passing around the box. Haaland is lost most of the time and he can't use his speed because the opponents almost never give him that space. He now has to play more like Lewandowksi and he doesn't have the quality when the ball is crossed in high like Ronaldo with his headers. It is a terrible game for him and he doesn't receive any great assists.
I would be very surprised if suddenly Manchester City rises out of the ashes and plays like they use to do in the past. It isn't a team that has a short term crisis. It is more like a team that needs an overhaul and an adjusted strategy or otherwise Haaland will remain toothless along with his teammates.
