Sunderland have signed centre-back Danny Batth from Championship side Stoke City on a free transfer.
Whilst at Wolves, he captained the side from League One to the Premier League turning out 212 times for the club.
"I'm very happy that this deal is done because this is a juggernaut of a football club," he said.
"This is the perfect set-up for me. I'm really looking forward to playing in front of the home supporters and I've already spoken to the head coach, who has tried to sign me in the past.
"When the opportunity arose, I thought it would be the perfect option to crack on and do well.
