Alexander Buttner is leaving Manchester United - because new boss Louis van Gaal doesn't rate him. Van Gaal's arrival at Old Trafford has convinced left-back Buttner to leave United - with Dinamo Moscow his likely destination. Buttner, 25, is turning his back on United because he feels he has no future under van Gaal, who has consistently overlooked him for his Holland squad. Signed from Vitesse Arnhem two years ago by Sir Alex Ferguson as back-up for Patrice Evra, Buttner has made just 28 appearances for United. With Evra having extended his contract for a further season and United confident of signing Luke Shaw, Buttner knows the time is right for him to move. The much-maligned defender claimed he had been voted United's man-of-the-match in half of his appearances for them, despite never looking convincing in two seasons. Buttner said: "Van Gaal never gave me the chance in the Dutch national team, despite being voted man of the match 14 times at Manchester United. "Apparently he is not very confident about me. So I think this is the right moment to leave." Buttner's agent, Alexander Bursac, admitted his client staying at United was not a viable option.
