Indeed, despite Brentford not valuing his services enough to dissuade him from leaving the club this summer, not one but two west London rivals are reportedly keeping a close eye on his managerial status.
Fulham, meanwhile, are keeping an eye on the Brentford boss in case Kit Symons' position at the club becomes untenable.
Fulham have struggled of late under Symons and, despite his hero status when he took the job at Craven Cottage, there has been discontent in the stands in recent weeks - especially following their home defeat to Ipswich Town last weekend.
Michael Laudrup would be favourite to land the QPR job should current boss Chris Ramsey not be appointed long term, say the Standard, but Warburton's summer departure from Brentford has reportedly alerted both QPR and Fulham.
Should a move take place, then, the 52-year-old wouldn't have to move far. Nor would he have to move divisions - unless QPR stay up and act upon their interest in him quicker than rivals Fulham.
