The BFI have tagged this early Mitchell & Kenyon footage of Manchester United (from their excellent archive on youtube) as having been shot during the 2-0 victory over Burnley at Turf Moor, on December 6th, 1902.
Several things about this claim do not seem to correlate with the video, however.
About 10 seconds into the video, is that Ernest Mangnall emerging from the tunnel and waiting to the left as the players follow him out? Does the sixth United player out of the tunnel not look a lot like Sandy Turnbull? Neither of those two were at United in 1902.
Also, the goalkeeper appears to be wearing a different shirt to the outfield players (this only started to happen around 1909).
Could this footage possibly be from either United's 3-2 win on 10th March 1909 or Burnley's 2-0 win on 15th January 1910 instead?
