The perception was that, with the departures of David Villa and David Silva, Valencia would not be anywhere near the force they once were. And yet Unai Emery has led his men to the top of La Liga, and they are bouncing after a 4-0 win in an opening Group C away trip to Turkish side Bursaspor.
They are unbeaten in 11 home European matches, although they won only five of them, while United have won just once in 18 visits to Spain, drawing eight and losing nine.
"It’s going to be a difficult match," Fletcher told manutd.com. "People say it’s not the same Valencia because they’ve lost Villa and Silva. But we’ve seen at United that you can lose good players and others come in and step up to the mark. We’ve seen that from them this season, they’re top of the league in Spain and they’ve made a fantastic start in the Champions League."
