An Andriy Shevchenko penalty gave Ukraine a 1-0 victory over 10-man Tunisia in World Cup Group H on Friday, assuring the east European side of a place in the last 16.
Shevchenko rifled home the spot kick in the 70th minute after referee Carlos Amarilla of Paraguay ruled the striker had been brought down by Tunisian defender Karim Hagui. Replays showed the Ukraine striker had tripped over his own feet.
Needing a win to qualify, Tunisia suffered a major blow in first half injury time when striker Ziad Jaziri was shown a second yellow card for a foul on Anatoly Tymoshchyuk.
But Ukraine, needing only a draw to be sure of joining group winners Spain in the second round, struggled to make the most of their advantage in a scrappy game at Berlin's Olympiastadion.
Coach Oleg Blokhin's side will play France, South Korea or Switzerland in the second round, depending on the outcome of matches played later on Friday.
Ukraine's best opportunity of the first half came in the 22nd minute when midfielder Tymoshchyuk burst into the penalty area but Tunisian goalkeeper Ali Boumnijel beat away his left-footed shot.
Tunisia's best efforts came from set pieces but they showed little to suggest they could win the game. Hamed Namouchi struck a curling free kick in the 19th minute but Ukraine goalkeeper Oleksander Shovkovsky caught the ball cleanly.
