Contesting their maiden Champions League campaign, Como sent a resounding message that they are not merely there to make up the numbers. Away to Lens on matchday four, Cesc Fabregas' side flew out of the traps to head into the interval with a commanding three-goal cushion.

The visitors broke the deadlock seven minutes in when Tasos Douvikas steered home from close range, with an assist from Perrone. The Greek striker struck again in the 32nd minute, latching onto a byline delivery from Valle to seal his brace with a clinical side-footed finish.

The irrepressible Nico Paz put the result beyond doubt in the 40th minute. From an acute angle, the Argentine unleashed an exquisite right-footed effort to net the third, capping a thoroughly dominant first-half display from the Italian outfit.
