Roy Keane says that he does not expect any more new faces to arrive at the Stadium of Light during the transfer window.
Phil Bardsley and Rade Prica joined Sunderland last week, taking Keane's number of January signings to four, following the loan signing of Jonny Evans and the arrival of Jean-Yves M'voto from Paris Saint Germain.
The Black Cats boss now feels that he has a squad capable of surviving in the Premier League and will not delve back into the market, despite being knocked back in his efforts to bring in a number of other potential targets.
"I'd be very surprised if we were to add to the players we've brought in the last week," he said on Sky Sports News.
"If I was a betting man, I would say keep your money in your pocket.
"We tried hard with one or two other players, we made some good bids we felt, but it just wasn't to be.
"We've managed to bring in one or two this week in terms of Bardo (Bardsley) and Prica.
"Two players with good attitudes who wanted to come to the club and hopefully will do a good job for us over the next few seasons."
Keane also confirmed that his former Manchester United team-mate Quinton Fortune is continuing to train with the club and a decision as to whether to offer the South African a deal will be taken next week.
"I know Quinton well," Keane said.
"He's come back from a bad injury so I invited him up to have a look around and he's been training really well for six weeks.
"He's due to play in a reserve match this week and we'll make a decision on Quinton next week."
