I don't think Chelsea can stand a chance against man city current form, playing against wolves was quite easy for them because wolves are not in a good form at the. Moment, Their victory against the away team was expected. But losing five matches in a row isn't really a good record enough to play against Manchester city but my best guess is that the game between both teams would end as a draw. Manchester city also needs that game to give them a boost so it's not going to be any easy game for both teams, but I would go with Manchester city to win or draw.
The confrontation between Maresca and Guardiola should have been interesting from the very beginning, the teams went through different stages, from the peak of form to the decline of different forms, but now it seems they have found their game and are ready to show their best game. Both teams are attacking, so there may be many goals, I don’t know who will win in such a game, probably the one who will cope better in defense.
