Blackpool have continued their squad strengthening with the signing of Costa Rica midfielder Jose Miguel Cubero.
Leeds boss David Hockaday has described attempts to sign Chesterfield defender Liam Cooper as "dead in the water".
Sunderland have secured a loan deal to take midfielder Ki Sung-yueng from Swansea for the rest of the season.
The 24-year-old South Korean international becomes the Black Cats' 11th signing.
Ki, who will join up with international team-mate Ji Dong-won at the Stadium of Light, has been allowed to leave the Welsh club despite making 38 appearances last term.
Ki first arrived in Britain back in 2009 when he left FC Seoul for Celtic - impressing in Scotland's top flight and prompting Swansea to fork out around £6m for his services last summer.
