The Ireland striker moved to Liverpool for 19 million pounds (USD 37.9 million; euro24.1 million), which could have risen to 20.3 million (USD 40.5 million; euro25.7 million) depending on his success during the four-year deal. But he struggled at the club he supported as a boy, scoring only seven goals in 28 appearances.

The Reds are believed to have accepted 16 million pounds from Spurs after rejecting an offer of about a million pounds less on Sunday night.

Liverpool manager Rafa Benitez didn't even include Ireland's record scorer in the squad for two of the last three games, including Sunday's 2-0 victory over Chelsea.

The 28-year-old Keane's six years at Spurs was his longest spell with a team following stints with Wolves, Coventry, Inter Milan and Leeds.

"It was a difficult decision to make to leave Tottenham in the summer - it proved not to be the right move for me," Keane said. "I know some Spurs fans will feel I let them down by leaving but I can assure them I shall be giving my all for this club. This club has terrific fans and I want to repay them for all their support. We've got to get on and fight our way up that league table."

Spurs is 14th in the 20-team Premier League, just one point above the relegation zone. Keane scored 107 goals for Spurs and helped them win the League Cup last season, but he will miss this year's final on March 1 against Manchester United after playing three minutes of Liverpool's third-round victory over Crewe in September.

Concluding the deal took on greater urgency for Spurs after striker Jermain Defoe injured his foot in training before Saturday's 3-2 loss to Bolton.

"Unfortunately he will be out quite a while it seems so it was important we got Robbie in," Redknapp said. "We are much stronger now and we have a squad that can do the job for sure."

Defoe returned to White Hart Lane earlier this month after a year at Redknapp's former club Portsmouth, and last week defender Pascal Chimbonda rejoined the club after two seasons at Sunderland.

When Keane left in the off-season, then-Spurs manager Juande Ramos, who was fired in October, had been hoping to use the fee from Liverpool to lure Arshavin.

But talks with Zenit St. Petersburg stalled over the price tag - and north London rival Arsenal experienced the same problems with the Russians in recent months.

Zenit had announced that the deal collapsed, but Arsenal manager Arsene Wenger told Sky Sports News that the move would be concluded.

Arshavin, one of the stars of last year's European Championship, was already in London in an effort to seal a move.

Heavy snow across the country hampered some of the deadline-day deals as some players and officials struggled to travel to meetings, medical checks and signings.

But the Premier League said deals that could not be completed before 1700 GMT because of the weather could potentially to be finalized after the deadline if it was proved they had been agreed in principle.

Chelsea manager Luiz Felipe Scolari signed winger Ricardo Quaresma on loan from Inter Milan until the end of the season to help to fill the void left by Joe Cole, who is out for the rest of the campaign with a ruptured knee ligament.

The 25-year-old Quaresma, who played under Scolari with Portugal, can play on either flank and his arrival could bring some much-needed width to a side that lost at Liverpool.

Others completed deals:

- French midfielder Olivier Dacourt joined Fulham from Inter Milan on loan for the rest of the season.

- Portsmouth signed Greece international Angelos Basinas from AEK Athens until the end of next season.

- Manchester City forward Jo joined Everton on loan until the end of the season.

- Newcastle exchanged Charles N'Zogbia for Wigan defender Ryan Taylor after the winger fell out with Magpies manager Joe Kinnear.

- Portsmouth signed Fanis Gekas on loan from Bayer Leverkusen with a view to a full transfer.

- League Championship leader Wolves signed Hearts defender Christophe Berra on a 4-year contract.
