Socceroos midfielder Tom Rogic and Celtic are out of the UEFA Champions League following a narrow loss to Bayern Munich on Tuesday.
Celtic needed to beat or draw against Bayern to have the chance of progressing to the Round of 16.
However the game did not start off to plan at Celtic Park, with Kingsley Coman scoring after just 22 minutes to put Bayern ahead.
Celtic battled in the second half, with Rogic coming on in the 64th minute.
The substitition helped, with Celtic finding an equaliser through Callum McGregor 10 minutes later.
But the 1-1 scoreline lasted just three minutes as Javi Martinez scored the winner for the Bundesliga champions.
However, Celtic are still in a good position to qualify for the Europa League, with a draw against Anderlecht in Matchday 6 enough to see them through to the Round of 32.
