West Ham are expected to announce the signing of Freddie Ljungberg on Monday.
The Hammers have called a press conference for Monday afternoon where they are expected to unveil Ljungberg as their latest new signing.
West Ham made a move for Arsenal ace Ljungberg after losing new signing Julien Faubert to a serious Achilles injury.
Upton Park boss Alan Curbishley has been keen to bolster his midfield options after losing Yossi Benayoun to Liverpool and he has moved to lure Ljungberg across London.
Ljungberg's future at Arsenal has been the subject of speculation all summer with the Swede not guaranteed a regular spot in Arsene Wenger's side.
Fiorentina and Manchester City had been linked with the attacking midfielder, but it appears West Ham have won the race for the 30-year-old's signature.

Freddie questions Arsenal's ambition
Freddie Ljungberg has questioned Arsenal ambition after leaving the club for West Ham.
The Swede, who was the club's longest serving player prior to his move to Upton Park, felt the time was right to move on after nine years in North London.
Ljungberg admitted the departure of Thierry Henry played a part in his decision to leave and he also questioned the club's failure to match his own ambitions by bringing in new players.
"Two years ago when I signed my last contract we talked a lot about the future and about bringing great players to the club," said Ljungberg. "Despite building the new stadium we wanted to stay top in England and do well in Europe.
"For me that didn't really happen.
"I stayed because I wanted to stay loyal to Arsenal. But when Henry left this summer it felt like the end for me unfortunately.
"I felt like all the unbeaten players (from Arsenal's 'invincibles' of 2003/04) had left. I wanted to be loyal but I felt like it was the right time.
Despite his doubts over Arsenal's plans for the future, Ljungberg admitted it was a wrench to leave the club.
"I've been there for nine years, almost 10 years," continued Ljungberg.
"It's a big thing for me and I feel it in my heart a little bit.
"When I spoke to the boss, he wanted me to stay.
"But at the same time, I feel it had to be something very, very special for me to leave.
"I want to go forward and, with the people I have around me, I think it's going to be really good."
