Premier League referee Mike Dean had a night off whistling duties on Monday - and spent it watching his boyhood club in the playoffs.

Dean was part of the travelling contingent of Tranmere fans for the second leg of their League Two playoff semi-final clash against Forest Green.

The official was also at the first leg, sat up in the stands, but the Sky Sports cameras caught him on the terrace and singing along to chants as the Merseyside outfit booked their place in the final at Wembley to face Newport.

And the cameras panned in his direction once again as the full-time whistle blew, and showed him stood on the terrace railing punching the air.

While his eccentric refereeing has polarised opinion over the years - fans were unified in praising Dean for following his local club and getting in the spirit of things with his fellow supporters.

"Referee Mike Dean in with the Tranmere supporters tonight at Forest Green and caught on camera singing, brilliant," one tweeted.

Another added: "Mike Dean in the Tranmere Away end at Forrest Green is top drawer."

Dean hit the headlines earlier this season when he brandished his 100th red card in the Premier League.

He sent Ashley Young for an early bath for a second bookable offence during Manchester United's defeat at Wolves on April 2.

His first match as a Premier League referee came in September 2000 when he took charge of Leicester's clash against Southampton.

It took until April 14 of that campaign to dish out his first red card, sending off Newcastle's Nolberto Solano for handball in the Magpies' match against Ipswich.

The longest-serving active top-flight ref, Dean averages a dismissal every five games, more frequently than any of his current colleagues.
