Crystal palace has always been a difficult opponent for Manchester City. But I didn't expect Manchester City to surrender a 2:0 lead after 70 minutes has been played. Sometimes I begin to wonder what you are looking for wen you are 2 goals ahead. Just protect the goals you have scored and forget to score more.
Manchester City are not a team like that, if they are leading especially against a lower level team to them like Crystal Palace, they will still want to add more goals. They are amongst the team in the top table that always score plenty goals and it always gives them advantage in goal difference. I am sure they never expected Crystal Place to comeback from 2-0 down. The final minutes penalty was the most shocking to them, because they knew the match was going to end in a draw when the penalty was given because there was no time left again to fight for a comeback.
