Everything is possible in football. People failed to see this record of Manchester City against the big clubs in the Premier League this season. People just believe Manchester City will end up lifting the Premier League title because they have won it in past seasons. Either Arsenal wins the Premier League trophy or Liverpool wins it this season.
I agree with your take. The Gunners are also stand a chance at winning the title this season and according to OPTA, a super computer who makes predictions, it gave Arsenal an 18.8% chance of winning thanks to their performance on Saturday when they won Brentford. Although Man City still has the higher percentage of 45.9% I strongly believe that anything can happen to turn things around. Many fans are expecting City to take their revenge when the Gunners travel to the Etihad on the 31st of March but maybe shocked to see that Arsenal came fully prepared.
