But it is understood that other clubs have also made moves for the wing duo.
Blackpool boss Paul Ince is reluctant to let his son leave, whilst Scots winger Phillips is another key member of the squad.
However, former boss Ian Holloway - fresh from promotion - is keen to add both players to his squad, and he knows just what both are capable of having signed for the pair during his time at Bloomfield Road.
Holloway, though, does have competition to sign both players.
Cardiff City are believed to be stepping up their interest in Ince, whilst Bolton boss Dougie Freedman wants Phillips.
It is also understood a number of other clubs are ready to test Blackpool's resolve over the duo.
