Argentine striker AlejandroDominguez, who scored a superb goal in the 1-1 draw with Inter, was brought back to the club after falling out with Zenit boss Dick Advocaat and has responded with a rash of goals.
Valencia coach Unai Emery did not wait to make changes and pushed two strikers up front by sending on Roberto Soldado, who had dropped to the bench after the defeat by Barcelona, for AlejandroDominguez at half time.
