Slovakia survived a late rally from Russia to secure a 2-1 win at Euro 2016 and blow Group B wide open.
The rank outsiders in a group also including England and Wales, Slovakia did the damage late in the first half.
First Vladimír Weiss, formerly of Manchester City, cut in from the left with 37 minutes on the clock to lash past Igor Akinfeev from Marek Hamsik’s excellent ball before the Napoli man turned goal scorer, firing home a goal of the tournament contender on the cusp of half-time from Weiss’ ball.
However, Russia ensured it was a nervous finish to the match when Denis Glushakov headed past Matus Kozacik with 80 minutes gone.
The result means Slovakia now have three points after two games, while Russia remain on a point.
England face Wales in Lens on Thursday.
Meanwhile, Admir Mehmedi led Switzerland’s comeback as the nation grabbed a 1-1 draw against Romania, leaving them just a point away from a guaranteed place in the last 16.
Vladimir Petkovic’s men could have qualified for the knock-out stages for the first time with a victory in Paris, but fell behind to Bogdan Stancu’s first-half penalty – Romania’s second spot-kick of the tournament.
Mehmedi brilliantly levelled the scores after the break, preventing Romania from recording just their second win at a European Championship.
Switzerland looked the more likely to win it from there, but failed to make their pressure count and will conclude their group campaign against hosts France.
Romania on the other hand, will surely need a win in their match against underdogs Albania if they are to extend their tournament.
