Spurs are believed to be eyeing the three stars as new boss Mauricio Pochettino looks to kick off his reign at White Hart Lane.
Bony is being dubbed as his main target, with the Ivorian forward seen as the ideal man to lead the line for the Lilywhites next term.
The returning World Cup ace is valued at around £25m-£30m by the Swans, who are in no rush to sell after securing his signature just 12 months ago.
Davies is also being mooted as a serious option for the London club, who are desperate to solve their long-standing left-back problems.
The Wales international has been a star for Swansea since making the starting slot his own, and at 21 he still has plenty of miles in the tank.
Vorm is the final Liberty Stadium star in Spurs’ plans, with the Dutchman being dubbed as a replacement for the outgoing Hugo Lloris.
Although the latter names are not valued as highly at Bony, Garry Monk still wants around £20m for the pair, taking the threesome’s price tag close to £50m.
Reports have suggested that Gylfi Sigurdsson – who enjoyed a loan spell in South Wales during 2012 – could be available to head in the other direction, which may reduce the potential fees.
