London: Sevilla kept its UEFA Cup title defence on track while 2005 champion CSKA Moscow was eliminated and Ajax's poor European season finally ended on Thursday. Sevilla had a comfortable 3-0 aggregate victory over Steaua Bucharest to reach the final 16. Striker Aleksandr Kerzhakov scored the only goal of the second leg when he headed past goalkeeper Cornel Cernea in first-half injury time off a cross from Andreas Hinkel. The match marked a disappointing return for Steaua to Sevilla's Ramon Sanchez Pizjuan stadium, where it lifted the European Cup in 1986 by beating FC Barcelona on penalties. Three other Spanish clubs Osasuna, Celta Vigo and Espanyol also made the fourth round. However, CSKA Moscow lost 1-0 to Maccabi Haifa to exit by the same aggregate score. Meanwhile Ajax beat Werder Bremen 3-1, but it couldn't overcome its 3-0 first-leg loss and exited the championship. Leonardo, Klaas-Jan Huntelaar and Ryan Babel scored for Ajax in Amsterdam, but it wasn't enough to stop the German club advancing. The loss was the culmination of a poor European campaign for Ajax, which failed to qualify for the Champions League group stage. Ajax won the last of its four European Cup titles in 1995; it also won the 1992 UEFA Cup. AZ Alkmaar, Bayer Leverkusen, Newcastle, Benfica, Shakhtar Donetsk, Rangers, Paris Saint-Germain, Lens and Braga also advanced on Thursday. But no Italian teams qualified after Parma and Livorno lost.
