Manchester City can win the Premier League title with or without Keven De Bruyne. Liverpool, on the other hand, has excellent attackers who can produce; they can play effectively and score goals even without Salah. As a result, they may win the league. However, since Arsenal defeated both Manchester City and Liverpool this season, I will also include them in the title race. They have an impressive squad that can win the league.
Manchester City still has Erling Haaland, who is one of the best players in the English league, so I think when Kevin De Bruyne is injured and can't contribute fully on the pitch, there are still some great players who provide good passes for the attackers to execute, even though Erling Haaland has just scored a goal. in the final minutes, but at least Manchester City managed to win this match.
For Liverpool, I see that luck is on their side because the opponent they are facing is a team with not very good strength, so it is normal for Liverpool to score a lot of goals.
Maybe you forgot when Kevin de Bruyne was injured no one could replace his role we even saw Manchester City out of top 4 a few months ago but after Kevin de Bruyne recovered from the injury to everything changed and Manchester City back to the struggle. Erling Haaland is a great player but he is not optimal without Kevin De Bruyne so these two players need each other. Now they are struggling to get rid of Liverpool at the top of the standings and we don't know how this season is over.
