Viktoria Plzen 2 Sporting CP 1 (aet, 2-3 agg): Battaglia header sends visitors into quarter-finals Ryan Benson 04:37 16/3/2018 Getty Images Rodrigo Battaglia’s extra-time goal proved crucial, as Sporting CP beat Viktoria Plzen 3-2 on aggregate despite losing 2-1 on Thursday. Sporting CP have booked their place in the quarter-finals of the Europa League thanks to a 3-2 aggregate win over Viktoria Plzen, as Rodrigo Battaglia got the vital goal in extra-time in Thursday’s 2-1 defeat.The Portuguese side’s luck appeared to have deserted them when Bas Dost saw a penalty saved in second-half stoppage time, sending the game to extra-time after Marek Bakos’ brace had wiped out Sporting’s 2-0 lead from the first leg.But Jorge Jesus’ men stepped things up a notch in the first half of extra-time, making the most of their superiority with Battaglia’s header on the stroke of the interval, and Plzen – who needed another two goals in response – were left deflated.
