Veteran defender Sol Campbell has sealed his return to Arsenal by signing an initial contract running until the end of the season.
The 35-year-old former England international has impressed in training with the Gunners in recent times, having been a free agent after ending an abortive spell with League Two Notts County.
Manager Arsene Wenger told the club's official website:"We are delighted to have signed Sol Campbell until the end of the season. For both club and country, Sol's career just speaks for itself.
"He is a hugely experienced and intelligent footballer, who will bring a great amount of quality and knowledge to our squad. Sol as a player and a person will be an enormous asset to us.
"Sol has been training with us since September and during this time he has shown he still has the required fitness, hunger and passion to compete at the top level."
Meanwhile, Wenger has swooped to snare yet another young prospect, snapping up 17-year-old midfielder Samuel Galindo from Bolivian side Real America.
"I'm looking to send him out on loan," Wenger added."We have a few clubs in mind.
"Galindo is a player who has good technique, he's intelligent, 6ft 2in tall, left-footed with good stamina.
"He is a central midfielder who can give good passes. He has good vision too which we like here."
