Maybe at the moment Man City's goal productivity is indeed declining. This happened since the start of the season because at that time De Bruyne had not returned. But after De Bruyne returned, Man City began to rediscover their best form. But unfortunately Haaland was then injured. And currently Haaland has recovered and has played in several matches. But unfortunately the sharpness he had as a spearhead has not yet returned completely. So we can say that Man City is not as good as last season. But they are still strong contenders for the title this season along with Arsenal and Liverpool. It's just that Man City might start to get better and better. But I doubt Liverpool because this team now has many injured players. Meanwhile, Arsenal seems like they have improved again recently.
Have you given up hope that Liverpool will win the title this season? Their injury should not have made one believe that they would be unable to maintain first place until the end of the season. They've worked hard to get to that point, so I don't expect them to simply disband after experiencing an injury crisis, which every club is bound to face on occasion. Arsenal, Liverpool, and Manchester City are still contenders for the Premier League title, and I don't see any weak teams among them based on how they've performed in league games. We have about twelve games left for each team, so I still believe the league is wide open for any of the teams to win and not disregard any of them as not being potential of the league title.
All these setbacks are bound to happen to any team in the league and the only difference that it makes in these teams is how they are able to manage these injuries of which I think Liverpool have really done quit a good job and they are really doing well at that too and with the way the league is turning to one can vividly say that have all the possibility and potential to hold on to that 1st place slot.
