Swansea boss Roberto Martinez has hinted he is ready to rest players for his side's Carling Cup fourth-round tie against Watford.

The Swans beat the managerless Hornets 3-1 at the Liberty Stadium in Sunday's Championship fixture and are now preparing to host Watford for the second time in three days.

Martinez could opt to leave out some of his key players and said: "We have to assess the individuals and see how they recover first but to have 52 hours from one kick-off to the next is ridiculous.

"We have many players who haven't had as many minutes as we would like and who have been working hard in training and opportunities like these are the perfect way to show how good we are."

Thomas Butler (hamstring), Andrea Orlandi (thigh), Marcos Painter (cruciate ligament) and Dorus De Vries (fractured jaw) all remain sidelined for the Swans.

Watford caretaker-boss Malky Mackay will be without on-loan defender Darren Ward.

Ward started the 3-1 defeat at the Liberty Stadium on Sunday but will miss the rematch as he is cup-tied after featuring in the competition already for parent club Wolves.

That should see Leigh Bromby revert to centre-back with Lloyd Doyley returning at right-back.

Midfielder John Eustace picked up his fifth booking of the season on Sunday but is available and will miss the clash with QPR at the weekend.

Jon Harley is back after a one-match ban of his own while another loanee, Southampton's Grzegorz Rasiak, is available for the Hornets.

Scott Loach is out with an abdominal injury while fellow goalkeeper Mart Poom is still on the treatment table with a shoulder problem. Midfielder Gareth Williams remains sidelined with a long-term cruciate ligament injury.
