Ghana's World Cup striker Asamoah Gyan has signed for Sunderland from Ligue 1 club Rennes, in a deal believed to be a £13.24 million club record signing.

Despite Rennes' website claiming that a deal was secured, Sunderland's own page suggested that the move was not yet completed.
At 5.30 pm on Tuesday, a statement read: "Sunderland AFC have not yet completed a deal for Asamoah Gyan. Officials continue to work hard behind the scenes."
Yet within 15 minutes, Gyan was announced as a new signing and he replaces Darren Bent, signed for £10 million last summer as the club's most expensive signing.
"As anyone who has watched Ghana recently or who watched the World Cup will tell you, Asamoah is a real livewire," Bruce said. "He had a fantastic tournament in the summer and a lot of European clubs sat up and took notice.
"I have been very keen to bring in another striker to add to the quality we have, but only when we felt the deal was right. We feel this is a great deal for the football club and Asamoah really wants to be here and in the Barclays Premier League, so I'm delighted he has joined us."
Gyan's arrival is timely as Sunderland manager Steve Bruce has confirmed that forward Fraizer Campbell has been ruled out for at least six months due to a cruciate ligament injury.
"He has ruptured his cruciate knee ligaments so he's going to be out for at least six months,'' Bruce told Sky Sports News. "It's a tragedy. He was just starting to show what he was about. But make no mistake he'll be back and he'll be firing again.''
Gyan scored three goals for his country at the 2010 World Cup, where he achieved infamy after missing a last-minute penalty against Uruguay.
Sunderland boss Bruce needed to bolster his frontline after selling Kenwyne Jones to Stoke for £8 million. Gyan, 24, joined Rennes from Udinese in 2008 and scored 14 goals for the club. He is loking forward to playing alongside international team-mate John Mensah.
"Quite unfortunately, when I joined Rennes he left only ten days later to sign for Lyon," Gyan said. "I have already met him here and I have played with him in the national team for over seven years.
"He is like a big brother to me and is always advising me. He is a great guy off the field as well as on it. "He is a joker - he knows me well and I am a joker too, a big one. We joke together a lot when we are in the national team. The atmosphere here is very important to me."
Sunderland have recouped £3 million by selling young striker Martin Waghorn to Leicester City.
