Louis van Gaal's defence is watertight at the moment, even if markers are letting him down.
Manchester United today kept another clean sheet, their eight in 12 games this season, as they beat West Brom 2-0 at Old Trafford.
Jesse Lingard scored his first for club, before Juan Mata wrapped up the points with a last minute penalty.
However, the scores were level at half-time, which might explain why Van Gaal was in a rush to get to the dressing room to scorn his team.
That spelt bad news for this youngster, who waited to get the United manager to sign his jersey.
However, the poor lad's marker didn't work, and Van Gaal wasn't about to wait around for a replacement.
