United v Arsenal preview..

United have been temporarily dislodged from the top of the table by 'happy Harry's' boys, Portsmouth, following a narrow 1-0 win away at Charlton on Saturday.

The reds will get chance to reclaim top spot if they beat Arsene Wenger's Arsenal when they visit Old Trafford on Sunday afternoon, prior to which the Premiership's other big two, Chelsea and Liverpool lock horns in West London at the Bridge earlier in the afternoon.

Both of tomorrow's big games are intriguing to say the least. Arsenal have really struggled in the early league games this season, but they're coming off the back of a good away win in midweek, in the Champions League against Hamburg.

United have started the best of the big four, the reds are unbeaten on 12pts and easily have the best goal difference. United have two serious injury concerns, as both Park and Giggs are out, but Ronaldo returns after being suspended in midweek. He will be key to opening the door. Fergie might well start with Richardson on the left, or he may even play Evra or Rooney on the flank.

Arsenal have of course recently lost Ashley Cole to Chelsea, so Ronaldo should find it a bit easier to get behind Arsenal's back four. Officially, Henry is an injury doubt for the Gunners, but it will come as no surprise if he's fit to play.

AS for the other big game of the day. This game will be really interesting, Liverpool beat Chelsea in the Community Shield in August, and of course the season before last, Liverpool knocked Chelsea out of the Champions League, so there's a few scores to settle as far as Chelsea are concerned.

Chelsea have been winning this season, but they haven't been convincing. Liverpool are coming off the back of a derby day mauling by Everton and it's likely Rafa Benetiz will ring the changes, especially up front for Liverpool, new signing Kuyt is likely to partner Craig Bellamy. Those two could be a real handful once they get going.

I'm not a betting man, and to be honest I'm the world's worst at predictions. Tomorrow, I'm backing United to beat Arsenal, by the odd goal in three and I expect the other game to be a scoring draw.
