Well judging from the way Manchester United played their last match against Arsenal, which is an improvement compared to last season. If they continue playing like that which enables them to create more chances in each game then the goal will come. Their attackers needs to be more clinical so as to convert those chances created. I just know that if a team creates chances even defenders will score goals.
That was in previous seasons, when Manchester United was not yet in such a prolonged crisis, but in the last seasons they have been losing to them in the Premier League and in the FA Cup, so the whole statistics should be taken into account, especially from the recent seasons. Fulham, by the way, had a pretty good preseason and managed to draw away against Brighton, which I also consider a very good result.
