Onus on Villarreal to attack Wolves

VfL Wolfsburg will hope that missed first-leg chances will not cost them in their UEFA Europa League round of 32 decider at home against Villarreal CF, after having only a 2-2 draw to show for last week's trip to Spain.

• The German champions passed up a string of great opportunities before Marcos Senna (43) put Villarreal ahead. Grafite (65, 84) then moved the visitors ahead on the night, but Marcos Ruben levelled (85) almost immediately.

Previous meetings
• The sides met for the first time in the first leg. Villarreal's only previous experience of German opposition came when they beat Hamburger SV 1-0 home and away in a 2004 UEFA Intertoto Cup semi-final. Wolfsburg, meanwhile, lost both legs of their only other tie against a Spanish side, going down 2-1 away and 3-2 at home to Club Atlético de Madrid in the 1999/00 UEFA Cup third round.

Match background
• Villarreal successfully negotiated the last-32 stage of the UEFA Cup twice in successive seasons in 2003/04 and 2004/05 – advancing to the semi-finals and quarter-finals respectively. But they fell at the round of 32 two seasons ago, losing on away goals to eventual winners FC Zenit St Petersburg.

• Villarreal have won two and lost two of their four European away fixtures this season. Wolfsburg's three 2009/10 UEFA club competition home games have ended in a win, a draw and a defeat.

• Wolfsburg made it to the UEFA Cup round of 32 last season but lost to Paris Saint-Germain FC, going down 2-0 away and then 3-1 at home. The reigning German champions have yet to win a springtime fixture in UEFA club competition.

Team facts
• Both clubs have changed coaches since the end of the group stage.

• Ernesto Valverde, a losing UEFA Cup finalist as both a player and coach with RCD Espanyol (1987/88 and 2006/07), was dismissed at Villarreal at the end of January, with highly rated B-team boss Juan Carlos Garrido replacing him.

• Wolfsburg removed their boss Armin Veh a few days earlier, with reserve-team coach Lorenz-Günther Köstner being placed in temporary command while the German champions seek a permanent successor.

• Villarreal's United States-born forward Giuseppe Rossi and Wolfsburg's Nigerian striker Obafemi Martins were team-mates at Newcastle United FC in the 2006/07 season.

• The winners of this tie will face the victors of the contest between FC Rubin Kazan and Hapoel Tel-Aviv FC in the round of 16 on 11 and 18 March, playing the second leg at home.

Penalties
• Wolfsburg have never been involved in a European penalty shoot-out.

• Villarreal have triumphed in both of their UEFA club competition penalty shoot-outs, beating Torino FC 4-3 at home in the 2002 UEFA Intertoto Cup and Atlético 3-1 in the 2004 edition.
