It could come down to penalties on Thursday night as Arsenal face Sporting CP with a Europa League quarter-final place at stake.
Following a 2-2 draw in last week's round of 16 first-leg in Portugal, the tie is delicately poised heading into the decider at the Emirates Stadium and with the away goals rule already scrapped by UEFA at the beginning of last season, all signs are pointing towards an entertaining game.
As per UEFA rules, if the scores are level on aggregate after 90 minutes as well as 30 minutes of extra time then a penalty shoot-out determines the team that qualifies for the next stage of the competition and another draw is the only result that would allow for this scenario to come to fruition.
