15 matches of the round of 16 stage were played on Thursday in the UEFA Europa League.

Bern's "Young Boys" team achieved a surprising victory at home, overcoming St. Petersburg's "Zenit" 2-1 after conceding an early goal.

Nicolas Lombaerts scored in the 20th minute and put the Russian champions ahead, but soon after the break, Senad Lulić equalized, and in the fourth minute of added time, Emmanuel Mayuka from Zambia, who came on as a substitute, secured the victory.

Furthermore, "Zenit" finished the match with ten men, as Vladimir Bystrov was sent off with two yellow cards.

Another Russian team, Moscow's "Spartak", had to travel to Switzerland, where they were defeated 3-2 by "Basel".

A victory was also secured by Moscow's CSKA with Lithuanian Deividas Šemberas playing the full match, as they defeated Salonika's PAOK 1-0 at home.

Meanwhile, Kazan's "Rubin" club, defended by Lithuanian Giedrius Arlauskis, lost 0-2 to Enschede's "Twente". The Lithuanian national team player was helpless against the goals of Luuk de Jong and Peter Wisgerhof.

"Liverpool" played a dull match away against Prague's "Sparta" ending in a goalless draw, while "Porto" defeated local "Sevilla" 2-1.

Portugal took the lead after a goal from Jorge Rolando in the 59th minute, and although Frederic Kanoute equalized with a header, the winning goal was scored by Freddy Guarin.
