Referee Graham Poll has informed the Football Association he saw no evidence of misconduct during the tunnel bust-up at Old Trafford on Wednesday.Players of both sides sprinted into the tunnel after Blackburn's Robbie Savage had chased Rio Ferdinand at top speed following a dig by the Manchester United man.But by the time Poll and his assistants arrived on the scene, any problem had been sorted out, giving the Tring official nothing to report.With Greater Manchester Police also advising the FA they will be making no complaint either, it is difficult to envisage any sanctions being brought against the two clubs or their players.Soho Square officials will investigate the matter further to see if they can uncover any evidence but at this stage it seems the incident will just be allowed to rest.And, according to Ferdinand, that is exactly what should happen anyway.'It was handbags,' Ferdinand told The Sun.'We had a little debate. It was the sort of thing that goes on all the time.'It was nothing to get excited about and I am sure Robbie would agree.'Savage was annoyed at the harsh treatment he received from the United players, who in turn felt the Welshman was making the most of any physical contact to get them into trouble.Ferdinand appeared to grab Savage as they made their way off during the interval of United's 2-1 win and after a brief delay, the Blackburn man quickly set off in pursuit.'It wasn't a dirty game,' insisted United defender Wes Brown.'It was a semi-final. If it wasn't competitive you would be disappointed.'Both teams were up for it and there were a few tackles going in - but you expect that in a semi-final.'
