Sunderland boss Roy Keane admits they're yet to close any of the deals they're working on.
He said: "There's no news yet on the transfer front. We have worked really hard and everyone knows I spoke to players over the weekend, and that went well.
"There are still one or two loose ends to be tied up at the Spurs end with one or two of these players, and hopefully it won't drag on too long.
"I would like a few positive decisions over the next couple of days, but I have to say I was very impressed with the four players when I met them, and we look forward to the news over the next few days.
"I have to say the club have made some very good offers and fingers crossed we can get across the finishing line."
