Manchester City provided more shocks as the lost two nil at home to Middlesborough. Southampton who have been so well also lost three goals to two to Crystal Palace.
So Arsenal played there game a day later and Arsene Wenger got the memo that it was not the time to play a weakened squad so he picked a full strength squad and it paid off as Arsenal beat Brighton by three goals to two.
The losses by three of the top teams has made it more realistic possibility that Arsenal can retain their title.
