Sunderland manager Roy Keane has been busying himself with a number of deals in the transfer window as he bids to bolster his team's chances of making the Championship play-offs in May.
Sunderland goalkeeper Ben Alnwick has joined Tottenham Hotspur in a deal taking Spurs' Marton Fulop in the other direction.
Roy Keane's side will pay £500,000 for the Hungary goalkeeper after he signed a three-and-a-half-year deal following a successful loan spell.
Highly-rated youngster Alnwick heads to White Hart Lane for £900,000 rising to £1.3million depending on appearances.
Sunderland have also sold Liam Lawrence to Stoke for an initial £500,000.
Meanwhile, Sunderland have also signed Luton Town midfielder Carlos Edwards in a £1.4million deal.
Edwards joined the Hatters in 2005 from Wrexham and made 74 appearances, scoring eight goals.
The 28-year-old also performed impressively for Trinidad and Tobago at last summer's World Cup.
