Sporting Lisbon are on the verge of qualifying for the Champions League as they lead 1-0 away at CSKA Moscow in the second leg.
The Portuguese side won 2-1 in the first leg, and have now added a crucial away goal to that total.
CSKA had the first chance of the game as Mario Fernandez crossed for Seydou Doumbia, but he shot wide at the near post from close range as the Russian side dominated early on.
However, they were hit on the break by Lisbon, who took the lead 10 minutes before half time.
Joao Pereira slipped a ball through for striker Teo Gutierrez, and he neatly found the bottom corner from a narrow angle.
