Manchester United and Arsenal have failed to take advantage of Chelsea's inactivity in the snowbound English football Premier League when they were held to draws by Birmingham City and Everton.
United have come from behind to draw 1-1 at Birmingham while Arsenal rescued a point with a last-gasp 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.
