West Ham United chief David Sullivan is delighted with their deal for Blackburn Rovers fullback Lars Jacobsen.
The move was arranged on Tuesday, but checks were made to ensure the relevant paperwork had been submitted before the 6pm deadline.
The green light from the Premier League was received, meaning the 30-year-old Denmark right-back moves to Upton Park on a free transfer.
Belgian goalkeeper Ruud Boffin has also arrived, on a two-year contract from Dutch side MVV Maastricht, along with Thomas Hitzlsperger, Tal Ben Haim, Winston Reid, Pablo Barrera, Frederic Piquionne and Victor Obinna.
Sullivan told club website: "We have combined youth with experience this window and are pleased with the work we have done, even in these challenging times for the club."
