(CNN) -- English Premier League big-spenders Manchester City have continued their summer recruitment drive with the signing of Arsenal's Ivory Coast central defender Kolo Toure on a four-year contract.
Toure was the final member of Arsenal's 2004 Premier League title-winning side still at the club.
The 28-year-old arrives from the Gunners for a fee reported to be in the region of £16m ($25m) following seven years with the north London club -- and is the final link with the 'Invincibles' Arsenal side of 2003-2004 which stormed to the league title without losing a match.
Toure passed a medical on Wednesday before completing the necessary paperwork and will be unveiled to the media on Thursday. Blog: Manchester City can be title contenders.
Manager Mark Hughes told City's official Web site: "I am delighted to welcome Kolo to the club.
"It is no secret that we have been looking to strengthen our defence, and in Kolo I feel we have recruited a world-class player. He brings a wealth of Premier League experience."
"Kolo has been a central figure in a very strong Arsenal team for many years. I have been an admirer of him for a long time. He is strong, quick, reads the game well and will be an influential figure in the dressing room," Hughes added.
Hughes turned to Toure after his efforts to bring in England captain John Terry were rebuffed first by Chelsea, then by the player himself.
Toure's arrival is City's sixth signing of the summer. His former Arsenal team-mate Emmanuel Adebayor has already checked in along with fellow-strikers Carlos Tevez and Roque Santa Cruz, midfielder Gareth Barry and back-up goalkeeper Stuart Taylor.
City are reported to be lining-up one more defender, with Everton''s England international Jolean Lescott high on their wanted list.
Meanwhile, Manchester City defender Nedum Onuoha has moved to end speculation over his future by agreeing a new five-year contract.
The 22-year-old academy product had been rumored to be on his way out but has instead committed his future to City and pledged to fight for his place in the team.
"I was pleased by the way I played towards the end of last season but at the same time I don't think that level of form will be good enough to get me into the side this time around. I will need to improve again," Onuoha told the club's official Web site.
One player set to leave City is Bulgarian striker Valeri Bojinov, who is poised to join Serie A side Parma in a one-year loan deal.
