The 29-year old midfielder played under R’s boss Harry Redknapp at Spurs.
"That's initially (what the deal will be),” he told Sky Sports.
“I am fit and ready to go, it's a top club and I am confident the manager can make sure the club stays up.
"I know Harry well, spent a lot of time with him at Tottenham and know him well enough.
"It's a top club, has some good players and not in that bad a position. They're four points off safety and can definitely claw that back."
