Sir Alex says the Reds would be "foolish" to think Wednesday night’s Champions League Group C clash against Valencia will be easy.
Los Che currently top the Spanish Primera Liga and are unbeaten in their last 11 home games in Europe. Furthermore, United have only ever won away from home once on Spanish soil in 18 previous attempts.
“Valencia’s home record over the years has been very good,” Sir Alex told the journalists assembled at his pre-match press conference in Spain. “It would be foolish not to respect that. Spain has produced cup-winning teams for years and you have to recognise that. The standard of Spanish football has always been good, so yes, it’s a difficult place to come and win.”
The United manager saw Wednesday’s opponents first-hand last week when he flew to Valencia to watch the team play Atletico Madrid.
“I saw a very good team when I came here last week,” he said. “We expect a very difficult game – they’re top of the league and playing very well.”
The Reds enter the game with only a point after the first round of matches in Group C but Sir Alex remains confident United will qualify for the knockout stages.
“The 0-0 draw against Rangers was a disappointing result but we have five games left to try and qualify. We have a tough game tomorrow, but that’s the great thing about the European Cup – you face the best teams in countries like Spain, Italy and Germany. That’s what makes it a fantastic tournament.”
