Video: Manchester United stars complete 22-header challenge on pre-season tour

Eight of Manchester United's players showed off their skills by completing a header challenge while on their pre-season tour of the United States.

The group, which included defender Chris Smalling, headed the ball 22 times overall before successfully knocking it into a bin.

The challenge was captured on film by the Premier League giants' media team a day after the team sealed a 3-1 victory over Barcelona in a pre-season friendly in California.
