* Rosicky strikes in stoppage time to earn Arsenal draw
* Manchester United held 1-1 at Birmingham
* Only two Premier League games survive snowy conditions
(adds late Birmingham City v Manchester United match)

LONDON, Jan 9 - 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 on Saturday.
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 on
Sunday postponed, are fourth with 37 points from 20 games.
