Footage has emerged of trouble between fans and stewards during Manchester United fans' sit-in protest after Sunday's Manchester derby clash.
Man United and Man City played out a drab 0-0 draw that failed to offer much to entertain either club's fans, with the former still down in 13th and the latter unable to move into the top four.
It came at a time with neither side in particularly good form, which was evidenced by the lack of real quality on the pitch at Old Trafford.
United fans had already planned a sit-in protest at Old Trafford for the game, and duly made their anti-Glazer views known.
