William Gallas, the former Arsenal captain who is now a free agent, has reportedly agreed terms to join the Gunners' north London rivals Tottenham.
The 33-year-old French defender is due to undergo a medical on Friday after agreeing to cross from the Emirates to White Hart Lane, The Times reported.
Gallas was left looking for new employers after Arsenal baulked at his high wage demands, reportedly 80,000 pounds a week.
But they have not put off Spurs manager Harry Redknapp who said last week: "His wages aren't a problem. He has not been greedy at all.
"His people have rung up and we spoke about it."
Traffic between Arsenal and Spurs has been light over the years, aside from Sol Campbell's acrimonious transfer to join Arsene Wenger's team also on a free transfer in 2001.
But Redknapp shrugged off any controversy there could be from Gallas crossing the north London divide.
"He's been an Arsenal player but he was at Chelsea before that and playing abroad before he arrived there.
"It's not like we would be signing Tony Adams. He's a good player and he would be a very useful addition to our squad."
With Jonathan Woodgate still out with a long-term groin injury and captain Ledley King plagued by knee problems that have the potential to limit his playing time, Redknapp has been keen to bolster his defensive resources.
Should Gallas complete a move, he would be Spurs' second summer signing, following that of Sandro.
The Brazilian midfielder's arrival in the UK is imminent after he helped Internacional win the Copa Libertadores.
