Earliest the Premier League won?

Although Manchester United have wrapped up the title before the end of April, it is by no means the earliest the Premier League has been won.

This is the sixth occasion the league has been secured before May, with the earliest coming in 2001 when United were mathematically out of sight on April 14, with five rounds left to play.
They beat Coventry City 4-2 at Old Trafford on the Saturday lunchtime and then nearest challengers Arsenal surprisingly lost 3-0 at home to Middlesbrough.

After tonight, there are four rounds of fixtures remaining, making this the third time the League has been sewn up at this point.
In 2000, United beat Southampton 3-1 at The Dell to cross the line with four matches left and they went on to win by a record 18-point margin from Arsenal.
And in 2004, Arsenal's 'Invincibles' gained the point they needed at Tottenham in a 2-2 draw with a quartet of games still to come. They eventually finished 11 points ahead of Chelsea.
