Liverpool are understood to be hopeful a recouping much of the £4.5million they outlaid for Lambert last summer.
However, Tottenham are expected to face stiff opposition for the 33-year-old's signature, with West Bromwich Albion manager Tony Pulis publicly declaring his club's interest in Lambert.
"Rickie is available. Liverpool have made that known," Pulis said.
"We'd be interested. It's very important that we get players who will score goals, Rickie's got a great goalscoring record.
"From what I can gather from people at Liverpool his fitness levels are very very good, and he is desperate to play football.
"He didn't play last year so it's like bringing a brand new car out of the garage if we did sign him. Just putting a bit of petrol in it and letting it run."
