UEFA have opened disciplinary proceedings against Atletico Madrid and Bolton following the crowd disturbances which marred their UEFA Cup tie at the Vicente Calderon last Thursday.

Fighting broke out inside the stadium although Wanderers were quick to point the finger of blame at the Spanish police, insisting their fans had been subjected to "a number of assaults and unprovoked baton charges before, during, and after the game".

Official reports have been submitted to the UEFA Control and Disciplinary Body, which will decide on the matter at its next meeting on Thursday, March 20.
