Gland Slam Sunday facts March 21 2008
The Premier League's top four all meet each other on 'Grand Slam Sunday' for the second time this season.
Leaders Manchester United host north-west arch-rivals Liverpool, with the Red Devils' title challengers Chelsea and Arsenal facing each other at Stamford Bridge.
We take a look at some of the match facts ahead of these two crucial encounters which could well decide the destiny of the coveted title.
Manchester United v Liverpool
:: The Reds have not beaten United in the league since April 2004 when Danny Murphy's penalty decided the outcome at Old Trafford.
:: United have not conceded against their bitter rivals in the top flight since September 20, 2004 - and even then it came via John O'Shea's own goal in a 2-1 victory.
:: The Red Devils' biggest league victory over the Merseysiders came in April 2003 when they won 4-0 after the Anfield outfit had Sami Hyypia sent off in the fourth minute.
:: Liverpool have won only three times at the Theatre of Dreams in the Premier League. They have managed only 14 victories in 74 league meetings at Old Trafford.

:: Arsenal have won more matches at Stamford Bridge (23) than Chelsea (22) in matches between the two sides. That record is also repeated just on Premier League form, with the north Londoners leading five to four.
