THE Green Brigade returned to Celtic Park – after a three-match absence with another less controversial banner display, which has received the approval of a sporting superstar.

The Hoops' hardcore fans group were banned for home matches against Rosenburg and Hearts - following a Champions League clash with Linfield in which fans unfurled a controversial ‘paramilitary’ display.

But for tonight's Champions League qualifier match with Astana, the group steered away from any controversial displays.

Instead there was a motif inspired by UFC superstar Conor McGregor who takes on boxing legend Floyd Mayweather next weekend saying: "We're not here to take part. We're here to take over!"

It was an echo of the words of the Irishman who defeated Diego Brandao in 2014.

Then he said: “We’re not here to take part, we’re here to take over!”.

McGregor has retweeted pictures of the display to his 5.24 million followers.

Celtic have announced they were to close the "Green Brigade section" of their stadium for the next two matches at the end of July after "serious incidents of unsafe behaviour" in the match against Hearts on May 27 and the Champions League qualifier against Linfield.

The announcement comes a day after Celtic were hit with UEFA disciplinary charges over an alleged ''illicit banner'' and "blocked stairways" during their Champions League victory over Linfield last month. The pro-IRA display led to a £20,500 Uefa fine for the Scottish champions.

The ban affected 900 season-ticket holders in the safe-standing section of the stadium which houses the Green Brigade ultras group.

The club expressed their frustration over a pyrotechnic display during the final game of last season against Hearts.

A letter from Celtic to fans explaining the closing of the Green Brigade area said that the Safety Advisory Group of Glasgow City Council, which licenses Celtic Park and comprises members of the council, police, fire and ambulance services had an emergency meeting after the Hearts game and communicated "their serious concerns to the club, which presented a risk to the renewal of the safety certificate necessary for the operation of the stadium and the capacity of the safe standing area.

But it later emerged that at a meeting of the Safety Advisory Group on Thursday, that the safety certificate had now been granted. It is understood it was felt that the two-game Green Brigade ban had sent a strong message from the club.
