Sunderland boss Steve Bruce hopes to expand his squad significantly by the end of next week.
The Sun says Bruce, who has also offered Blackpool's David Vaughan a contract, has agreed deals to sign Birmingham City midfielder Sebastian Larsson, Coventry keeper Keiren Westwood and South Korean striker Ji Dong-won.
Talks are continuing with Manchester United aimed at bringing Darron Gibson, Wes Brown and John O'Shea to Wearside.
And Liverpool are trying to reach a compromise over a loyalty bonus in David Ngog's contract before the Frenchman can complete his switch to the Stadium of Light.
