Tens of thousands of Manchester United fans are lining the streets to celebrate their team's 20th English league title and catch another glimpse of manager Alex Ferguson before he retires.

Jubilant United players were spending a second day with the Premier League trophy after lifting it Sunday following the 2-1 win over Swansea. That was Ferguson's final game at Old Trafford after nearly 27 years in charge.

An open-top bus bearing a "Champions 2013" logo set off from the stadium Monday under overcast skies. It is to make its way through the streets in a parade lasting more than an hour before arriving at Albert Square in the center of the city.

Ferguson's final game as manager is Sunday against West Bromwich Albion.
