MADRID (AFP) Manchester United look to end their miserable European record in Spain on Wednesday as they search for their first Champions League win of the season at Spanish league leaders Valencia. United have won just once in 18 matches in Spain against Spanish opposition, with their only win coming in the 2001-02 Champions League quarter-final first leg at Deportivo La Coruna. They will have their work cut out against an unbeaten Valencia side who have won four out of their first five league matches to top the Spanish top flight. United coach Sir Alex Ferguson watched his side labour to a 0-0 draw against Rangers in their Group C opener and will hope for more attacking bite at Valencia, as well as more defensive stability than they have shown of late. The three-time European champions have conceded seven goals in their last three league matches and will be well aware that Valencia trounced Bursaspor 4-0 in Turkey in their group opener. Yes, were concerned about the number of goals we have let in, said defender Nemanja Vidic. Over the last few years we havent conceded many goals. We always looked strong and we didnt give teams many chances. But in the last few away games we havent kept clean sheets, which is very disappointing. At the other end of the pitch, United will be missing both Welsh winger Ryan Giggs and England striker Wayne Rooney, after both players sustained injuries in the 2-2 draw at Bolton Wanderers on Sunday.
