John Brewin previews this week's Premier League action and highlights five key storylines in this edition of W2W4.
1. United face tough Watford examination
Manchester United vs Manchester City on Dec. 10 looks like the season's crunch game, but for that to be a chance for Jose Mourinho's men to peg back their neighbours, they must negotiate this week's tough schedule.
On Saturday, they travel to Arsenal. Before that comes Tuesday night's trip to Watford. When City visited in September, they barely gave Marco Silva's team a kick, winning 6-0. But the Hornets have been buzzing of late and are in eighth place.
