Manchester United have reportedly had £3,000 worth of footballs stolen from the club's Carrington training ground.

The North-West outfit are believed to have launched an investigation into the theft, which is thought to have taken place just after the club's training staff lined up the Nike Maxim balls ahead of a practice session.

The Premier League leaders are understood to have taken the matter into their own hands as opposed to alerting the Greater Manchester Police, according to Goal.com.

Reports have claimed that some of the balls have since been sold in the area.
