West Ham fans went into Sunday for once hoping Arsenal would beat Man United. They needed the Gunners to come through for them to keep the Hammers four points clear of United in fifth place in the Premier League.
In the end, Manchester United were 3-2 winners over the north London side as 18-year-old Marcus Rashford scored two and set up one.
But West Ham - and all other - supporters were still treated to a bit of fun, as United boss Van Gaal dived on the touchline.
He seemed to be making a point to the fourth official and Brady saw the funny side on Twitter:

When a follower joked about giving the dive a rating, Brady responded:
i'd have to give it more. especially as he hang on to his clip board at the same time! https://t.co/aTkZtuYknc— Lady Brady (@karren_brady) February 28, 2016
