Nottingham Forest haven't had a chance to do something in the game with Man City yet, but maybe they will have a chance after the red card... Of course they can't win the game, but there is hope that they will score a goal...
City are possession playing team and with that opponents doesn't has much chances. A team planning to win against City should be able to sharpen their attack enough to find goals in just few attempts because that is how it is when a club faces a side like City. Forest are not sharp enough and no wonder that they haven't found a goal against City till now. I think even with red card they wouldn't be able to find a goal.
