Celtic manager Brendan Rodgers has urged supporters to get behind the team after they drew with Crvena zvezda in their Europa League opener on Wednesday evening.
Half-time substitute Kelechi Iheanacho opened the scoring on 55 minutes, although Marko Arnautovic's equaliser meant the spoils were shared.
Celtic are back in Europa League action next Thursday as they welcome Portuguese outfit Braga to Parkhead on matchday two. They then face Sturm Graz at home on the third matchday.

Boss Rodgers has urged the fans to get behind the team ahead of what is a crucial set of fixtures.
"I think that the lift the supporters will give the team in these European games will be absolutely critical," he said after his side earned a point in Belgrade.
"We sensed it here tonight. And our fanbase, how fanatical they are, can really push us in this competition.
"Like I said, I cannot tell the supporters what to do and how to feel. But really, if they can really help us as a team, then that would be amazing because we will really feel the benefit of that.
"A packed-out Celtic Park can really help us over these coming games."
