Ronny Deila has warned Celtic fans about their behaviour after a series of flares were thrown before and during their Scottish Cup fourth round victory over Stranraer.
The game was slightly delayed due to the crowd disturbance, but once the game got underway, a brace from talisman Leigh Griffiths and a first Celtic goal from Carlton Cole got the club into the next round with a 3-0 win.
It is the continuation of a worrying trend associated with Celtic with the team having a recent history of this kind of behaviour. Fans have set off flares against Dinamo Zagreb and Fenerbahce in the Europa League in the last couple of seasons, with the latter still being pursued for charges by UEFA.
As part of the recent letting off of flares in Turkey, two fans were banned by the club indefinitely from attending matches. As well as this, Dundonian police recently put out a statement before the eventually postponed match between Dundee and Celtic at Dens Park warning fans against the use of flares.
In his post-match interview, Deila definitely stated that the behaviour was not welcome at Celtic matches.
As quoted by Sky Sports he said:
We don’t want this. It’s something that is making a bad reputation for the club. So this is absolutely something we need to get stopped. It is not positive for anybody and we, as a club, don’t want to have anything to do with this.
It’s not my job – but I’m a part of this club. We’ve talked about it a lot and we have to get it away from this club. I’m not from here so I don’t know what kind of sanctions we could face.
But what I can say is that it’s important we follow the rules – and that people are safe when they come to football matches.
That is why we have football as a cultural thing that everybody can be part of. Safety has to be the most important thing in every game we play.
The incidents certainly overshadowed reaction to the game from fans on social media, with many critical posts being fired at the Celtic fans.
There are currently no liability rules in force for the Scottish Football Association to use against Celtic, but the SFA, alongside the SPFL, created the ‘Flair not Flares’ campaign in August 2014 to try and encourage the eradication of the problem.
However, the organisation may want to set a UEFA-style precedence to attempt to combat the alarming rise in the use of these in Scottish matches.
