The stage was set three weeks ago at Lyon's Olympic Stadium: the Frenchmen ready for the onslaught of attacking prowess pulsating through a rampant Barcelona side, packed full of elite-level quality. Bruno Genesio's men particularly ready for the Catalan's number 10, Lionel Messi, to drive at them relentlessly for an hour and a half; to stretch their defence and test out their man between the sticks at every opportunity.
Punters filled their bet-slips with -2 handicap selections as the Spaniards were expected to run amuck in the east of France. A resilient performance from the hosts - which saw them stick to a strict game plan laid out by their man on the touchline throughout the entirety of the performance - meant that Barcelona left knowing they had it all to do in the return leg 22 days later.
With the game hanging firmly in the balance at 0-0, Wednesday night's clash at the Nou Camp was do-or-die for Barca. An away goal for the visitors would have been catastrophic for Ernesto Valverde's side: it would have made their job ten times more difficult and seen the possibility of progression in this season's Champions League massively hindered. Once again the stage was set, this time in the Spanish region of Catalonia - Barcelona's playground.
Lyon know that a lucky break could well decide the tie for them, but their mounting concerns over the man dubbed 'The Atomic Flea' have now intensified due to the fact they're now in the Argentine's backyard; the kingdom he's ruled over for the previous 15 years, like a lost group of school kids who have broken their compass' and lost their maps on an orienteering trip in unknown territory.
