FA Cup bring a lot of surprises every year, I will go here with " both teams to score and more then 3 goal`s". I agree both teams wish to win and M. United is a favorite here, but in my opinion playing on goals is better odd then just on M. United win.
C. Palace can score one goal, I don`t think they will be totally helpless here. I saw statistic for this game, and previous games say that M. United always win, in last 5 games between this teams 4 times M. United won ( C. Palace scored just one goal ) and month ago it was 0 - 0. I think its time for C. Palace to score again.
