Manchester United and Arsenal failed to take advantage of Chelsea's inactivity in the snowbound Premier League when they were held to draws by Birmingham City and Everton this afternoon.
United came from behind to draw 1-1 at Birmingham while Arsenal rescued a point with a last-gasp Tomas Rosicky equaliser in a 2-2 home draw with Everton.
The results left Chelsea, who had their match at Hull City postponed because of the icy weather, clear at the top with 45 points from 20 matches followed by United with 44 from 21 and Arsenal with 42 from 20.
Tottenham Hotspur, who also had their trip to Liverpool tomorrow postponed, are fourth with 37 points from 20 games.
