Sky Sports sources understand Watford are in advanced talks to sign Daniel Tozser and Samba Diakite.
Hungary international Tozser is due in England on Wednesday to put the finishing touches to a deal which will see him join on loan from Italian outfit Genoa.
The 28-year-old midfielder has not featured for Genoa in Serie A this season.
Likewise, Diakite is yet to play in the league for Queens Park Rangers this season and Harry Redknapp has stated that he would stand in his way.
Now Watford are close to finalising a deal for the Mali international, who has two years left on his current deal at Loftus Road.
