The midfield enforcer has been one of the Bhoys' most consistent performers over recent years, but he has struggled to scale those heights at the start of the new campaign, by his own admission.
Brown insists that he will be back to his best sooner rather than later, though, and has vowed to start playing at his best in the near future.
“I could play a lot better. Everyone has ups and downs in their career and it’s how you bounce back," he said. "I’m strong mentality and physically as well and I’ll come back stronger and fitter.
“We need a bit of luck. Football is about that and small details. If you get that one goal and then a second it can build confidence throughout the team and fans. We have a lot to go to reach where we were last season but hopefully we can hit those heights again.”
Brown is not the only Celtic player to start this season in poor form, with the side having suffered setbacks at home and abroad.
Although Leigh Griffiths has opened the campaign well, and has hit the back of the net on a regular basis, there are few others who can feel proud of their start.
Celtic have struggled so far and they currently trail Aberdeen in the Scottish Premiership as a result, and they have disappointingly dropped out of the Champions League again before the group stage.
Their search to find form will not be made any easier by their fixture list either, with a tough test against Ajax in the Europa League next up.
