Why penalty decisions went against Man Utd at Bournemouth

PGMO chief refereeing officer Howard Webb says the penalty decisions that went against Manchester United at Bournemouth were because of the difference in the "speed the attackers are moving at".Man Utd led twice on the south coast in March through Bruno Fernandes and a James Hill own goal, but Ryan Christie and a late penalty from Eli Junior Kroupi earned the hosts a point in an incident-packed match.
