And while the winger has been a bit quiet on the scoring front since 30 December - when he netted in the 5-0 win over former club Wigan - there's no denying his role in the Reds' recent successes against Milan, West Ham and Aston Villa.
Wayne Rooney netted from Antonio's crosses in all three games. The Reds' top scorer acknowledges, "My headed goals are probably all down to good wing play."
Meanwhile, Sir Alex Ferguson has praised his first Ecuadorian signing for working "his socks off" and giving opposition "defenders a real hard time. He's done really well for us."
Valencia will hopefully be on song again for Saturday's trip to Wolves, a game you can hear live on MUTV Online at 17:30 GMT before watching video highlights from midnight.
