Stoke City confirmed the capture of Michael Kightly from Wolverhampton Wanderers, as Wolves forward Steven Fletcher handed in a transfer request amid interest from Sunderland.

The Potters have also been given the go-ahead to sign American international Geoff Cameron from Houston Dynamo after the 27-year-old was granted a work permit at an appeals hearing at the Etihad Stadium in Manchester.

Kightly put pen to paper after agreeing to personal terms and completing a medical and joins the English Premier League club for an undisclosed fee. The 26-year-old expressed his happiness to remaining in the Premier League, after his former club Wolves were relegated last season.

"It's a great club; an established Premier League club, so I am delighted to be here," Kightly, who spent five years at Molinuex, told the club's official website.

"Any footballer wants to play at the highest level and I am grateful to Stoke for giving me the chance to stay in the Premier League.

"The club sold itself to me. What they have achieved over the past few years has been remarkable. Then there's the excellent facilities and, of course, the supporters.

"So, it's definitely a club that is moving in the right direction."

Stoke City manager Tony Pulis admitted he had been monitoring Kightly's progress for a long time. "There is nothing better than to have strong competition in all areas of the squad and Michael's arrival will give us that in the wide positions," Pulis said.

"I've long been an admirer of Michael, not only in terms of him being a provider, but also the fact that he gets his share of goals.

"Our two wingers, Matthew Etherington and Jermaine Pennant, have been brilliant for this club over the past few years, but they went off the boil in terms of goal-scoring last season, so we wanted to address that.

"Competition for places will bring the best out of them again and that is what Michael's presence will give us in that area."

Stoke were also delighted to see Cameron being given a work permit. "We are delighted that the appeals panel have approved the work permit and we are now in a position to conclude the transfer," Stoke chief executive Tony Scholes said.

"It's been a difficult period between agreeing the transfer deal and the hearing, most difficult for Geoff in particular because his life has been on hold.

"Thankfully though, we have now progressed to a point where Geoff can focus on the start to his career at the Britannia Stadium."

Meanwhile, Fletcher handed in a transfer request at Wolves after growing frustrated at the club's refusal to sell him, despite Sunderland reportedly putting in a £12 million bid Wednesday. "Just handed in a transfer request just to let the fans know where I am at right now.... #headsgone," the 25-year-old wrote on his Twitter account.

Wolves confirmed the transfer request, but insisted the player would not be sold, until their valuation is met by interested clubs. "Wolves can confirm that Steven Fletcher has handed in an official transfer request," a statement said.

"The player's frustration stems from the fact that several bids have been rejected for his services, none of which meets the club's valuation.

"As previously stated, no player will leave Wolves unless the club's valuation is met.

"Wolves will be making no further comment at this time."
