STEWART Regan, the SFA chief executive, has condemned the "misbehaviour" during the first Old Firm match of the season at Celtic Park on Saturday.

Regan, speaking from the UEFA congress in Athens where Aleksander Ceferin of Slovenia was elected president, called on “the whole of Scottish football” to act.

Effigies of Rangers fans were hung from the stands during a Ladbrokes Premiership game which was broadcast live by Sky Sports and which also coincided with World Suicide Prevention Day.

Rangers supporters group Club 1872 has written to the club board calling for them to ban Celtic supporters from attending Ibrox for the next Old Firm match on New Year’s Eve.

Rangers directors responded by describing the scenes as a “sickening and shameful display of outright sectarian hatred”.

Rangers supporters also trashed a toilet and sang The Billy Boys during a game which Celtic won 5-1 to move further ahead at the top of the Premiership table.

Peter Lawwell, the Celtic chief executive, stressed the Scottish champions operate to “the highest possible standards” and would deal with the incidents “in a professional and private manner”.

But Regan believes it is the responsibility of the national game as a whole to take action to prevents its reputation being tarnished again in the future.

Speaking to Sky Sports, he said: “Areas of misbehaviour, unacceptable conduct, call it what you will, in my opinion, have got no place in the game.

“I have seen the pictures on TV and in the newspapers, of effigies being hung up in the stands, and also evidence of banners being displayed and toilets being trashed.

“This has got no place in modern football, it is not acceptable, and it is something I hope the whole of Scottish football will take seriously and try to do something about it.”

Regan welcomed the appointment of Ceferin as Michel Platini's successor. “He visited us in Glasgow a few weeks ago and talked us through his manifest," he said. "He was keen to unite all 55 associations behind a common vision and we believe he was the best candidate to unite UEFA.

“This is a guy who is not only president of the Slovenian FA but is a very successful lawyer and businessman running his own company back home in his native Slovenia.

“He has obviously impressed people on his travels. He has got a very comprehensive manifesto and plan and is keen to make an impact."

Meanwhile, Davie Weir, the Rangers assistant manager, has escaped SFA punishment for his outburst in the Old Firm game on Saturday.

Weir was facing a touchline ban after being sent to the stands by referee Willie Collum during the second half of the Premiership match.

The former centre half felt that Celtic right back Mikael Lustig should have been booked for a challenge on Rangers winger Barrie McKay.

He mistakenly believed the Swede had been yellow carded by Collum earlier in the match and would have been ordered off.

The incident occurred just after Philippe Senderos, the Swiss centre half who was making his debut for the Ibrox club, had been red carded for a deliberate hand ball.

Tony McGlennan, the SFA compliance officer, could have issued Weir with a notice of complaint and a potential touchline ban for his conduct in a game which Rangers lost heavily.

However, he has instead let the Scot off with a warning and has written to the 46-year-old informing him of his decision.

Weir will be free to take up his position alongside Mark Warburton in the Rangers dugout on Saturday in the Premiership game against Ross County on Saturday.
