Robin van Persie nailed his colours to the mast at Manchester United's Christmas party on Saturday.

Van Persie displayed his loyalty to the Red Devils with a festive rendition of 'Glory Glory Man United' during their Christmas party at Rio Ferdinand's Rosso restaurant in Manchester , says the Daily Mail.

Alex Ferguson paid £24million for the striker and is unlikely to be regretting the move.

Since his transfer from Arsenal, the 29-year-old has scored 15 goals in 21 games for his new club, taking them six points clear at the top of the Premier League.
