Manchester United legend Gary Neville says Birmingham City deserve a points deduction after an ugly pitch invader incident on Sunday.

A fan ran onto the St Andrew's pitch in the ninth minute and appeared to strike Aston Villa playmaker Grealish from behind.

Neville wrote on Twitter: “The club are going have to take a huge punishment for this to act as a deterrent in the future.

“A points deduction or Empty stadium for 10 games!"

West Midland Police confirmed a suspect was arrested after the incident.
