Overview:After establishing a club record of 14 straight wins in the first half of the season, Arsenal have momentarily gone off the boil. A draw against West Ham and victories over Charlton and Queens Park Rangers make up Manchester United's record in London this season. Past form at Highbury favours United and a close encounter. They have won there three times in the last four seasons, all by the odd goal, as was Arsenal's victory in the corresponding match last season.
