Manchester United and Arsenal renew their rivalry on Saturday, live on Sky Sports 1 HD, but who are the Soccer Saturday pundits backing?

The Gunners have found no Premier League ground more difficult to conquer than Old Trafford, last winning at the stadium a decade ago, while Arsene Wenger is yet to beat Jose Mourinho in a competitive fixture.

However, the visitors arrive in superior form, unbeaten since the opening weekend of the season and in position to go top of the Premier League with a victory, while United are already eight points off the pace with just five wins from 11 games.
