O'Neill confirmed forward Camilo Duran is fit and available having missed training on Wednesday after travelling to London for a visa in relation to a Colombia call-up. The Northern Irishman insists Celtic are looking to "get off to a decent start" in the Europa League and he may have to make changes to the side given the demands of this week, facing Rangers twice either side of this fixture amid a run of "seven games in 22 days". O'Neill conceded the players are hurting after exiting the League Cup at Ibrox last Sunday.
