I'm not sure if this is an important match or not what is clear is don't be too confident on one side. Indeed, Manchester City deserves to be the favorite to win because they have a better history and statistics it's just that sometimes the unexpected can happen for example they play young or new players well this can mess up our predictions so it's better to wait a few hours before the match starts to see the starting lineup. By the way so far the sportsbooks Stake.com prefer Manchester City and both teams to score YES and over goals are still the favorites to place bets, I don't think both teams think about playing defensively meaning the fight will go on until the last minute and let's wait for the next 4 days.
I think Guardiola used his young players in pre-season games because he did not want his top players to be injured before the Premier League season began. likewise, Ten Hag doesn't want to make use of his top players because few of the players they need to perform at a high level next season were injured in pre-season games, and it would be dangerous if any of their players sustained more injuries. However, based on the pre-season games played by both clubs so far, Manchester City surpassed Manchester United. Guardiola's young players performed much better than Manchester United's young players. So I believe it will be interesting to bet on Manchester City as the favorite to win.
Chelsea is a kind of team that is controlled by the fans and sometimes the owner of the team needs to be honest with his plan and stop what the fans say, Chelsea was defeated by Manchester City and many people are shouting and complaining about the new manager, what do people want him to do? He needs time to build his team so let's give him time and see what he’s capable of doing, the only complaint I have against Chelsea is they are selling some of their players and they need to think before selling them.
Enzo Maresca needs to learn from the pre-season game they played, plus the challenges he will face next season with the players the team provided to him. Chelsea is not a team that is patient with its managers, they are always interested in achieving good outcomes each season. I won't think about Maresca as a bad manager only because they failed the pre-season games, I believe Chelsea will recover and win their games.
