Former Liverpool striker Ian Rush has backed Michael Owen to be a goalscoring success at Manchester United.[LNB] Owen completed a surprise switch to Old Trafford on Friday night just two days after he became a free agent when his contract at Newcastle expired.[LNB] Rush told Sky Sports News: "It's a chance for Michael to get back and score some goals. He'll get chances for Manchester United and will score goals."[LNB] Injuries have ruined recent seasons for Owen and the England striker made just 71 league appearances for the Magpies since his move from Real Madrid in 2005.[LNB] However, Rush believes the move gives Owen an opportunity to return to form in front of goal after scoring just 30 times in all competitions in the north-east.[LNB] The former Wales forward added: "People have knocked Michael Owen all his career but he comes back bigger and better.[LNB] "People said he was finished years ago but he's a fantastic player who comes back stronger and better.[LNB] "It (the talk) won't worry him, I know the way he is and he doesn't have to prove anything anyway."[LNB] Former Liverpool favourite Rush - who scored more than 220 goals for the club in two spells either side of an ill-fated stint in Italy with Juventus - believes Owen would make a good impression were he to return to Anfield.[LNB] However, the 47-year-old added: "Personally, I'd like to have seen him at Liverpool but they haven't lost their best strikers. He (manager Rafael Benitez) will be happy with what he's got."
