I knew this would have been the result. Arsenals defense against top teams are frail whereas their offense is quite good but not much point if they let goals get in needlesly :/ Despite man utd not possessing the greatest attacking force right now (rooney not at best, berbatov being berbatov and who else? chiharito and macheda? they lack first team experience to be used against top flight teams) they still managed to get through a weak defense. Typical park ji-sung being the scorer, he has been a good constant player for ManU over the years but rooney missing that penalty... he has to get grips with himself and start playing well by atleast the latter part of the season
