Brendan Rodgers insists Celtic aren't 'daft' and know they need a result against Atletico Madrid. Celtic are looking to make a fist of it in the Champions League after their Spanish adversaries denied them of ending a decade-long wait for a home group win in the competition.
And while the daunting task of taking on Diego Simeone's side at the Metropolitano leaves the Group E challenge looking considerably harder, Rodgers goes to the Spanish capital with as close to a full complement as possible and on the crest of a wave.
But the Irishman is under no illusions that they have to take something if their hopes of qualification are to be kept alive.
Defeat could even dent their hopes of finishing third in the group and keeping the Euro adventure going until after Christmas in the Europa League, with Lazio hosting group leaders Feyenoord and already three points clear of the Scottish champions.
