Thousands of Celtic fans came together on Wednesday night to protest against the club's board. Despite Martin O’Neill’s swift return on Wednesday, just over 24 hours after Rodgers’ resignation, this did not deter fans from taking to Celtic Park and protesting the board’s actions and questionable attitude.

Signs saying ‘not another penny – no club merchandise, no catering, no paid events, back the team, sack the board’ being raised on Wednesday night.

One supporter said: "This collective is just a bunch of Celtic fans. I know it seems counterproductive for us to be protesting when a legend has just come back into the club, however at 73-years-old he has proven how bad the problems are."

The fan added further: "Everything we do is for the benefit of the club. This has been happening for years. This bunch of clowns behind us don't want to engage."

O’Neill’s first game returning as Celtic’s interim manager had the best possible outcome, considering the chaotic few days leading up to the Celtic v Falkirk match. Brendan Rodgers only resigned on Monday – the reaction from the board targeted blame towards Rodgers for the Hoops recent results. The exit was far from civil, with majority shareholder Dermot Desmond having a lot to say.

Despite the off the pitch rumblings, Celtic came back with a bang. A 4-0 win, with Johnny Kenny securing two of the goals within the first half. The score was further extended by Benjamin Nygren and Sebastian Tounekti, making it an effortless win in the end.

Interim manager O’Neill expressed the worries he had before the match. These were reasonable considering the circumstances, thankfully his anxiety was lifted due to the positive result.

During his post-game interview, he said: "I'm delighted, satisfied in the sense I thought we played very well. My anxiety has calmed somewhat, and it was nice to win. When you get a few goals in front you can perhaps enjoy the last 10 or 15 minutes, and it kind of brought me back.”

So, what’s next for Celtic, more specifically, the board? The likely answer is more mismanagement and placing blame onto whoever the next permanent manager will be. During the protest, there were posters highlighting six of the club's board members for recent faults. Celtic supporters know who are at fault, and there will surely be plenty more protests and chants against the board until there is substantial change.
