Ugly scenes at the Riverside marred Manchester United's 3-1 win over Middlesbrough on Sunday afternoon.
The clash was sparked when Rudy Gestede and Eric Bailly came to blows in the closing stages of the game.
As the Manchester United players walked down the tunnel after the final whistle they appeared to be caught up in a spat with the opposition.




BT Sport cameras showed pushing and shoving at the start of the tunnel, with Jesse Lingard restraining Ashley Young while Michael Carrick had to lead Eric Bailly away.
