The remaining half of the Champions League league playoff first legs were played out on Wednesday. The two biggest teams in action, Zenit St. Petersburg and Porto, both picked up wins.
Zenit won away against Standard Liège, with Oleg Shatov's early goal enough to guarantee a slim victory. With an away goal, the Russian side should have more than enough to book their place in the group stages. Meanwhile, Porto eventually beat a stubborn Lille by the same scoreline, with Héctor Herrera netting an away goal just past the hour.
Elsewhere, Celtic were held to a 1-1 draw in Slovenia by Maribor, though Callum McGregor's away goal means they have the advantage heading into the return leg. Danish outfit Aalborg conceded an away goal in their score draw with Cypriot side APOEL, while Slovakia's Slovan Bratislava drew 1-1 at home to Belarus' BATE Borisov.
The reverse fixtures are to be played next week, on Tuesday 26 August.
