Sorry mate but arsenal bottled it.
Team selection was wrong from the start, denilson and bender are shit and didnt add the usual fluidity of your play.
a couple unlucky decisions, the penalty shout remember was when the play was a full stretch and bramble looks like he tripped and fell at normal speed, it need a number of replays to confirm the slight push and your asking the ref with one view to get it spot on. The offside call looked onside but was a split second decision and they happen in many games.
this was a sunderland team that had lost 4 on the trot and looked to be lacking cutting edge. At the end of the day, Arsenal have themselve to blame for missing a golden chance.
