Celtic have endured a very difficult start to the new season with new manager Ange Postecoglou taking time to really get his reign going at Celtic Park.
There have already been two major defeats in the Scottish Premier League away at Hearts and then in the derby against Rangers last time out before the international break.
Those defeats have left Celtic already with a lot of work to do in the league if they are going to be able to regain their title from Rangers after last season’s poor performance.
They have also suffered the frustration of being knocked out in the Champions League play-off rounds with them losing to FC Midtjylland.
However, they have at least been able to reach the Europa League group stages after a difficult second leg away to AZ Alkmaar.
Celtic will be hoping to get back to winning ways when the campaign resumes, but while we wait to see if they can do that we have created a quiz to test your knowledge on which of these 18 famous faces support the Glasgow giants? Can you get 100%!
