Make sure there is no away goal

Rule number one of hosting your European opponents in the first leg.

Celtic will have to defend for their lives at times to ensure that they do not leak a goal that will hand the advantage to Roberto Mancini’s men – and when you consider that a 2-1 defeat for Inter would actually be a decent result for the Italians, you see how hard it becomes.

Celtic will have to make sure their desire to win the game and attack does not leave them exposed at the back against a side whose best form of defence is attack.
