Their 3-0 defeat of Everton gave them an unassailable lead at the top of the table, when coupled with Sheffield FC being held to a goalless draw by Durham.
The Black Cats clinched the crown with three games to spare, having won all but two of their games to date, losing at Everton and drawing at Aston Villa.
In the Southern Division, Arsenal are on course for the title ahead of Reading and Chelsea, with one win from their last two games likely to be enough.
The Gunners also have the League Cup final to look forward to on Saturday May 28th, when they face Sheffield FC at Sutton Coldfield Town’s ground.
