MILAN, April 16 (Reuters) - Juventus all but booked a place in next season's Champions League qualifiers thanks to a 3-0 win over Serie A strugglers Parma on Wednesday. David Trezeguet appeared offside when he tapped the ball in on 16 minutes after Mauro Camoranesi's header hit the post. Winger Raffaele Palladino made sure Juve took full advantage of their game in hand when he buried the second on the half hour and Stefano Morrone's own goal made it three before Parma defender Fernando Couto was sent off for protesting. Third-placed Juve have 64 points, 12 ahead of AC Milan in fifth with five matches to play. Claudio Ranieri's side are seven behind second-placed AS Roma, who occupy an automatic Champions League spot. Positions three and four earn a place in the Champions League qualifiers. A place in Europe's premier competition would be a good achievement for Juve in their first season back in the top flight following demotion for match-fixing in 2006. Hector Cuper's Parma, who were saved from relegation last season by then-coach Ranieri, are one point and one place above the drop zone. The original game was postponed last month when a Parma fan was knocked down and killed by a Juve supporters' coach on the way to the match.
