If we were talking about Chelsea years ago when Potter was working there and they were in bad form I was not going to give Chelsea any chance against a team like Manchte CIty because considering the coach and players they have in this team and based on their past performance Chelsea could easily lose this match but now since Chelsea is in the better form and they are even about to win the Premier league title while Guardiola is in a crisis with his team, I think Chelsea can have a gib chance in this match.
However is somehow Manchester City wins the game, they can decrease the pressure on this team after beating Chelsea.
It will be a big game and both teams will definitely try to win the game, Chelsea have had a big change in the season and maybe they are much better than Manchester City who are in a dip in form. But for this game I am more confident that it will end in a draw because of the performance of both of them which has decreased a bit. Pep Guardiola will definitely not let Chelsea get points easily and vice versa with Chelsea.
Even though Manchester City lost in the Champions League, it does not mean Chelsea can beat them easily. It will be a little bit more difficult for both of them and I think a draw is a potential that might be more likely to happen.
