Brentford manager Mark Warburton has revealed his fury after seeing what he described as a "shocking" decision go against his side in the 2-1 defeat to Watford on Tuesday.

James Tarkowski was adjudged to have fouled Odion Ighalo inside the box just before the break, allowing the Nigerian to beat Brentford goalkeeper David Button at the second time of asking, but Warburton was quick to place the blame on referee Graham Salisbury.

"What changed the game was that shocking penalty decision," the Brentford boss told members of the media. "The Watford player is running into the box, Tarkowski is running alongside him, his hands are up and the player goes straight to ground. There was no contact whatsoever.

"The referee's delay in giving the decision was to see if it was a yellow or a red. That is absolutely incredible. Our players are distraught in there.

"I hate to come across as having sour grapes because it is not that at all. The fact is my players and our 2,000 fans were fantastic tonight and deserved at least a point."
