QPR want Jordan Hugill back next season.
Striker Hugill scored 15 goals during his year on loan at Loftus Road from West Ham.
And Rangers would like him to be included in any deal with the Hammers for Ebere Eze.
The east London club are interested in Eze as well as Brentford winger Said Benrahma.
QPR, who believe Eze is worth at least £20m, are looking to sign at least a couple of forwards this summer.
They would like to sign Hugill either on loan or a permanent deal and believe their best chance might be if West Ham make a move for Eze, who is also wanted by Crystal Palace.
Hugill, 28, was signed by David Moyes in a surprise big-money move from Preston in January 2018 – weeks after QPR believed they were in with a chance of signing the player for around £1.2m.
Moyes returned for a second spell as West Ham manager last year, leading to some speculation that Hugill could be given a second chance.
But Hugill is not in Moyes’ plans and seemingly has no future at the London Stadium, having not started a Premier League game since his move to the capital.
He is therefore likely to be playing in the Championship again next season.
QPR lining up potential deals
QPR would also like to sign midfielder Luke Amos, who spent the season on loan from Tottenham.
And an approach was recently made to Wigan’s administrators for striker Kieffer Moore, who has attracted interest from a number of other clubs.
Meanwhile, Bright Osayi-Samuel is still mulling over a move to Club Brugge.
The Belgian outfit recently had an offer accepted for the winger, who has been keeping his options open.
Other clubs have been linked with Osayi-Samuel but none have so far made a firm move for him.
Centre-back a must for Rangers
While keen to bolster his attacking options, Warburton has admitted that bringing in a centre-back is a priority.
“Yes, it would be, and I’m saying it because young guys have had to step up like young Conor Masterson, who at the start of the season I felt needed to go out on loan,” Warburton told West London Sport earlier this week.
“You need to learn the ugly side of football, the demand for points and so on.
“He stepped up against Leeds, Swansea and Brentford and will be hoping to keep his shirt. I’ve never got a problem with that. There’s also young Joe Gubbins.
“But we need some physicality and some experience as well.”
