Stoke City have signed winger Michael Kightly from relegated Wolves for an undisclosed seven-figure fee.
"It's gone on longer than we'd have hoped for," Potters assistant manager David Kemp told BBC Radio Stoke.
"We had hoped to have him in for the start of pre-season. But we're just happy to get the deal completed."
Stoke have not disclosed the length of the 26-year-old former England Under-21 international's contract at the Britannia Stadium.

in November 2006, before signing for £25,000.
His existing contract with Wolves was due to expire at the end of the coming season.
After rediscovering his old form towards the end of last season after two injury-hit years following double knee surgery, he was keen to stay in the Premier League.

"It has been Michael's wish to seek a fresh challenge and try and remain in the Premier League if at all possible, rather than sign a new contract," said Wolves chief executive Jez Moxey.
"Given that reality, and the danger of losing Michael for nothing at the end of his contract, we reluctantly gave him permission to speak to Stoke."
Kightly, once a target for Manchester United before his arrival at Molineux, is one of three summer signings for Stoke.
They are still waiting on international clearance on Rangers midfielder Jamie Ness, and are also close to completing a £1.7m move for defender Geoff Cameron, 27, from MLS side Houston Dynamo after he was granted a work permit on Wednesday.
"It's our fifth season in the Premier League now and you're always looking to freshen things up to try and keep improving," added Kemp.
