A goal by Dynamo Kiev midfielder Andriy Yarmolenko gave Ukraine a 1-0 win over Poland and top spot - at least for an hour -- in their 2014 FIFA World Cup Brazil™ qualifying group.
Ukraine have 18 points from nine matches and are two points ahead of England, who were taking on Montenegro in London later on Friday.
Ukraine had midfielders Taras Stepanenko and Edmar cautioned in the opening eight minutes.
Poland came close to scoring when Kamil Glik had a 27th-minute header blocked by Evgen Konoplyanka.
In the 64th minute, Yarmolenko put the hosts into the lead, sending the ball home past goalkeeper Artur Boruc after Poland's Lukasz Szukala misjudged a cross by Konoplyanka.
Poland replied with a close-range header from Borussia Dortmund striker Robert Lewandowski which went over the crossbar in the 74th minute, but Ukraine held on for a valuable win.
