Wolves have announced the signing of centre-back Roger Johnson from Birmingham.
Johnson, 28, underwent a medical on Monday and has now signed a four-year deal at Molineux.
Wolves CEO Jez Moxey told the club's official website: "We tried to sign Roger two years ago when he moved from Cardiff to Birmingham and have been tracking him ever since.
"We are pleased to have signed what we believe to be an excellent player who represents good value for money for us. He fits the bill perfectly - a British centre-back in his prime, one with Barclays Premier League and cup-winning experience, a vocal, determined, leader-type who has played consistently well for a long time.
"We stressed that we would not rush to do deals this summer and would have to be patient in the pursuit of our targets, which has been beneficial to us.
"However, Roger has still joined early enough to give him plenty of time to get settled with his new team-mates and play in the pre-season games. We are delighted with the way it has worked out."
Moxey remained tight-lipped on the transfer fee, which was reported to be £7 million. "While we are sticking to our policy that all transfer fees agreed remain undisclosed, the reports concerning the deal with Birmingham are also inaccurate," he said.
Johnson said the lure of staying in the Premier League was just too great in his decision to leave St Andrew's.
He said: "I'm sure a few people will be disappointed that I've not stuck it out, but I'm 28 and I want to be in the Premier League for as long as I possibly can. Nothing against Birmingham – I had a great time there, the fans were great to me, but for me this just feels right."
Johnson is Mick McCarthy's third permanent signing of the summer following the arrival of Jamie O'Hara from Tottenham and keeper Dorus de Vries.
