QPR are interested in Legia Warsaw midfielder Ariel Borysiuk.
The 24-year-old, a Poland international, started his career at Legia and returned there in January following spells at Lechia Gdansk and German side Kaiserslautern.
Rangers want to complete the signing of at least one midfield player before their pre-season campaign begins with a friendly at Aldershot Town on 1 July.
They have spoken to Belgian club Oud-Heverlee Leuven about a potential deal to sign former Tottenham midfielder John Bostock.
And they have had an offer for Metz winger Yeni Ngbakoto, 24, turned down by the French outfit.
The two clubs remain in discussions and Rangers are hoping to take Ngbakoto to Loftus Road this summer.
They are keen too on Sehrou Guirassy, 20, but Lille are demanding a big fee for the France Under-21 striker after he impressed during the recent Toulon Tournament.
Rangers also remain keen to sign Brentford left-back Jake Bidwell and Huddersfield central defender Joel Lynch despite having had approaches for them rejected.
