In this season of boom and bust, Louis van Gaal will face a particularly torrid walk from dugout to changing room along the Old Trafford touchline should Manchester United suffer a third consecutive defeat, to West Ham United. It would also mean the wait for a 12th triumph in the Cup will extend to a 13th year. Slaven Bilic’s side have won their past four matches and there will be no surprise if this becomes five.
