O'Hara helped Wolves retain their place in the Premier League
Wolves have signed Tottenham midfielder Jamie O'Hara in a £5m deal.
The 24-year-old has agreed a five-year contract after enjoying a successful loan spell at Molineux during the second half of last season.
O'Hara scored three goals in 13 games, including one against Blackburn on the final day of the campaign that helped keep Wolves in the Premier League.
Manager Mick McCarthy said: "There was a dip in form at one juncture but he came strong again at the end."
An agreement had already been put in place for O'Hara to make his stay at Molineux permanent should the player and McCarthy wish to make that happen.
The former Portsmouth midfielder joined Wolves on loan in January and has played just behind the main striker in a 4-5-1 formation.
"I am delighted the deal has been done which will see Jamie become a permanent Wolves player," added McCarthy.
"It may have taken a bit of time to finalise all the details but it was always going to happen because we wanted to sign him and he wanted to come.
O'Hara said he was delighted to join Wolves following a "scary end to the season".
"It's going to be sad leaving Tottenham. I had a great career there and the fans were always different class with me," he said.
“I didn't even ask for a five-year deal ”
"I'll always support Spurs but it's one of those things. I had to move on.
"The chairman and the manager at Wolves put a lot of faith in me after I had been out for a long time with a back problem.
"I was put straight into the side and to make a permanent move now after a scary end to the season [narrowly avoiding relegation] is brilliant.
"I didn't even ask for a five-year deal. They offered me it. It is fantastic. It shows they wanted me and wanted me to be here for the long haul."
Wolves are also interested in Reading defender Matt Mills and Liverpool left-back Paul Konchesky, who spent the second half of last season on loan to Nottingham Forest.
