This defeat will cost Manchester City their position because if Chelsea and Newcastle win their matches, they will push City down to 5th position. However, football is full of surprises and one saw this coming. This is the second match that Southampton have played on a clean sheet out of their last 47 matches. This is Ike a big relief to Southampton.
Maybe you mean this is a draw. Yes but for City this draw is also a defeat. No one expected City not to beat Southampton. I also thought City would win easily in this match. Luckily I didn't bet on anyone in that match. This result is not good for City because their position in the UCL zone can be shifted by other teams. If Chelsea or Newcastle win the match then City's position will be shifted by them. And with 65 points it is not a safe position because if Nottingham Forest and Aston Villa can finish the match with a win then they are only 1 point behind City. I really regret that City failed to get 3 points. They should have been able to get 67 points and further secure their position in the UCL zone.
