The Blues disappointed over the weekend, dropping two points in a lackluster 0-0 draw at Sunderland. After second-place Southampton dropped three points to Manchester City though, the gap at the top of the table looks exactly the same.
Following the events of the weekend, the top of the table is starting to take the shape we expected it to before the season began. Chelsea still maintain a comfortable six-point gap at the top, but the team in second is now Manchester City, who will likely be Chelsea's closest competition for the remainder of the season.
Additionally, both Arsenal and Manchester United managed to close the gap on Southampton, with United in particular seeming to be finding a bit of form along the way. Louis van Gaal's side has now taken 17 points from a possible 24 in their last eight fixtures, a stretch which included matches against Chelsea, Manchester City, Arsenal, and Everton. Don't look now, but United could be poised to make a push toward the top as they have a run of more winnable contest without any League Cup or European interference.
Regardless, Chelsea would be best served by taking care of business against Tottenham at Stamford Bridge on Wednesday, assuring the gap at the top remains at least six points.
