Queens Park Rangers on look-out for mole

The tip-off appeared to work to Watford's advantage as they triumphed 3-0.

Rangers also conspired to leave their confidential pre-match tactical briefing document in the visiting dressing room after the game.

Contained in the notes was a list of "things that might hurt us", which identified Watford's long-ball strategy and the late runs of John-Joe O'Toole as potential threats.
