Blackpool have signed midfielder Andy Reid from Sunderland for an undisclosed fee, while also taking striker James Beattie on loan from Rangers.
But they managed to keep hold of captain Charlie Adam despite a last-ditch bid from Tottenham Hotspur.
Spurs manager Harry Redknapp said a deal was agreed but the paperwork was not completed before the deadline.
Blackpool had previously rejected a £6.5m offer from Liverpool for the 25-year-old Scotland international.
Redknapp told talkSPORT: "Daniel [Levy] rang me late on and asked if I like Charlie Adam. I said 'yes, he's a fantastic footballer'. He said do you want him, I said 'can we get him?'.
"We pushed on and tried to do it, Daniel was confident he could get it through. It went to the wire but we missed out by minutes.

"Daniel dealt with it. Apparently the boy was definitely up for coming...apparently the chairman couldn't get hold of two shareholders who had to sign the forms as well. It's just one of those things.
"But there's a chance we could go back for Adam in the summer."
Blackpool chairman Karl Oyston said the club maintaining its place in the Premier League was of paramount importance.
He told the Blackpool Gazette: "I want to give the town, the club, its supporters and the manager the best possible chance of maintaining Premier League status.
"It would be horrific if we all sat at the end of the season saying 'What if?' Now, no matter what happens, there won't be any 'what ifs?'.
"We will give staying in this league - and all the rewards that brings - our best shot. We go forward together and we won't have any regrets," he added.
Oyston also told BBC Radio 5 live he supported calls for the transfer window to be scrapped after a frantic final-day's activity.
"It's a time for desperation in agents and clubs and it's one of the things that directly contributes to poor football finance and governance and people just spend themselves into trouble sometimes," he said.
Blackpool bolstered their squad by signing 28-year-old Reid until the end of the season. He has made 70 appearances for the Black Cats.
Reid joined Sunderland from Charlton for £4m but has recently been on loan at Sheffield United. He started his career at Nottingham Forest before moving to Tottenham in 2005.
Beattie, 32, moved to Ibrox from Stoke in August but has made only seven appearances for the Scottish club.
He agreed a two-year contract at Rangers last summer with the option of a further 12 months and was the Scottish champions' first signing in two years.
The striker, who has five England caps, moved to Scotland after struggling to cement a regular spot at Stoke.
His switch came on the back of a much-publicised bust-up with Potters manager, Tony Pulis, in December 2009.
The Tangerines have also taken Zenit St Petersburg striker Sergei Kornilenko, 27, on loan for the rest of the season.
Kornilenko, a Belarus international, has recently had loan spells with Tom Tomsk and Rubin Kazan and will add to manager Ian Holloway's strike options.
Blackpool are currently lying in 12th spot in the Premier League with 15 games remaining in the season.
