Man utd v/s arsenal

Anyone here watched the match? Because i wanted to know why van gaal substitute ROjo for blackett.As a man utd fan , this sub was not a good one. Because blackett put an own goal.

The own goal was unlucky for Blackett - a cross that deflected off him and past the substitute goalkeeper.

sure it was unlucky...But man utd had the opportunity to take the 3rd place from arsenal. this would result a direct qualification for the champion league . now man utd had to pass through stage inorder to qualify . no its not sure he will win the match to qualify.

both are very good teams but prefer MU
