The Scottish champions conceded an away goal in the first leg against the Greeks and will likely need to be on top of their game to go through
Celtic will need to put in a strong performance against AEK Athens on Tuesday if they are to have a chance of progressing to the Champions League play-off round.
Brendan Rodgers's side were held to a 1-1 draw in the first leg of their third qualifying round tie against the Greek champions last week, meaning they need to score at least once at Athens Olympic Stadium in order to go through to the next round.
