Celtic have secured Tottenham striker Robbie Keane on loan until the end of the season.
Thousands of fans gathered at Celtic Park to welcome Keane to the Glasgow club on Monday night.
The striker was delighted at the signing, which Celtic hope will help them close the gap on league leaders Rangers.
Keane said: "The club is massive. I'm a Celtic fan. I always wanted to play for Celtic and it works for all parties."
The club also signed Diomansy Kamara on loan from Fulham and Morten Rasmussen from Brondby.
Keane joined Spurs in 2002, making almost 200 appearances and scoring 80 goals, before joining Liverpool for around £20m in July 2008.
He only played 15 times for the Anfield side and rejoined Spurs in February 2009.
His previous clubs include Wolves, Coventry, Inter Milan and Leeds.
Elsewhere, Manchester City signed England Under 21 winger Adam Johnson from Middlesbrough for a reported fee of £7m.
