Currently in second place, the Hornets are just a point behind league leaders Reading, having won their last two games before the international break.
Despite their high placing in the table, Watford's away form is a potential worry for Vladimir Ivic as his team have only one victory in five games on the road this season – against bottom club Derby County.
The Hornets have just one other win away from home in 2020, and that came against Bournemouth in January.
They travel to a QPR side who have lost only once in five home games so far this campaign, against the division's best away outfit Preston North End.
However points-wise, Rangers are as close to the bottom three as they are to the top six, which will give Warburton hope that anything can still happen as we approach the quarter-point of the season.
Saturday will be the first league encounter between QPR and Watford since April 2014, but they did meet in the FA Cup in 2018-19, when Etienne Capoue's goal on the stroke of half time gave the Hornets a 1-0 win.
Queens Park Rangers Championship form: LDLWWL
Watford Championship form: WDDLWW
QPR should have Bright Osayi-Samuel back available after he missed the defeat to Blackburn with a groin injury.
Meanwhile George Thomas is back in full training following a thigh problem, but it may be too soon for him to start a league game, with Mark Warburton keen for him to get minutes for the development team first.
A number of Watford's squad – such as Craig Cathcart, William Troost-Ekong and Ismaila Sarr – have been away on international duty and only returned to training on Thursday, but should still feature on Saturday.
Will Hughes has had a setback in his return from injury so will not be involved, but Troy Deeney played in a friendly against the club's Under-23s last weekend as he continues to build up his fitness.
Queens Park Rangers possible starting lineup:
Dieng; Kane, Barbet, Dickie, Hamalainen; Cameron, Carroll; Adomah, Chair, Samuel; Dykes
Watford possible starting lineup:
Foster; Troost-Ekong, Kabasele, Cathcart; Femenia, Garner, Capoue, Cleverley, Sema; Sarr, Gray
We say: Queens Park Rangers 0-2 Watford
The Championship summit is in Watford's sights, and that could drive them to earn a rare victory away from home. QPR have only won three times this season and they are likely to struggle against the quality in the Hornets side.
