Wembley Stadium has issued a statement vowing to "take appropriate action if required" for the pitch invasion which followed Millwall's victory over Bradford in the League One play-off final.

Hundreds of Lions fans entered the Wembley field at full-time after Steve Morison's 85th-minute fired their club back into the Championship and some goaded the Bantams' players and manager Stuart McCall, who claimed he was close to physically confronting them.

Morison was among those who condemned the antics too and Wembley responded with a statement on Saturday evening promising to look into the incident and work with security to ensure the scenes are not repeated.

A series of posts on their Twitter account read: "We do not condone the scenes at the final whistle of today's League One play-off final, which saw some fans enter onto the pitch.

"The matter was dealt with by Wembley Stadium's security response team and no injuries were reported.

"It is an offence to enter the pitch and we will be working with the relevant authorities and Millwall Football Club in an attempt to identify those individuals involved and we will take appropriate action if required.

"We will also undergo a thorough debrief with our security team to help avoid repeat incidents for upcoming events."

But Millwall forward Aiden O'Brien defended the club's fans.

O'Brien, who progressed through the London club's academy, refused to join in the condemnation.

"No, they have the right to do that you know," he said.

"They've been supporting us all through the season. They should celebrate as much as we celebrate.

"It's a team thing and they're part of the team. They can run on the pitch in my eyes for all they want, they deserve to."
