Chelsea are full of surprises but at this time I don't expect any surprise between them and Manchester City, even against them and Tottenham Hotspur the only took the advantage of two red cards and get motivated to score goals, but Manchester City are different from Tottenham that they played nine against eleven with, so their victory in the match can not justify the next match. I quite agree with you that if really Chelsea perform they may end draw but right now Chelsea to win Manchester City who currently on the top of the table and also one of the strongest team in English Premier league with the highest goal scorer this season, I will not said anything folder let just wait for tomorrow and see whether Chelsea will perform miracle and win or Manchester City will win.
Chelsea's success in beating Tottenham deserves appreciation, considering that was the first defeat for Ange squad this season. However, this victory was a victory where luck played a bigger role, yes, that's the red card I mean. On the other hand, Pochettino squad latest victory will not mean much if in their other matches they will fail, they will again sink at the hands of Man City.
On paper, I don't doubt the quality of Pep Guardiola squad at all, and I also can't underestimate Chelsea. Who would have thought that a surprise would happen again, and we would all be surprised again by the results.
But whatever the scenario, I think betting on City winning is still very safe, because we know the risk is smaller. Chelsea only benefited from playing at home, on the other hand I saw many things that made Pep's squad worthy of being superior.
