Newcastle have announced the signing of South Korea captain Ki Sung-yueng, with the midfielder's move from Swansea to become official on July 1.
The 29-year-old has signed a two-year deal and will join on a free transfer when his contract expires.
"I'm so pleased I can join the club," Ki said on the Newcastle's official website. "I was always pleasantly surprised when I came to St James' Park to play against Newcastle - there is a great atmosphere and the passion from the fans is a great support to the players.
"Everyone knows how big this club is so I'm really looking forward to playing with my teammates and for the fans."
Swansea City have appointed Ostersunds manager Graham Potter on a three-year contract
Roberto Martinez insists Kevin Mirallas had no intention to hurt Modou Barrow with the tackle that saw him sent off during Everton's goalless draw with Swansea City.
Second-half substitute Mirallas lasted just 112 seconds on the pitch before being dismissed for a challenge that referee Stuart Atwell deemed was reckless and over the ball.
But Martinez is adamant that the Belgian winger was simply demonstrating the enthusiasm he demands from all of his substitutes.
Swansea City boss Garry Monk was determined to focus on the positives of his side's performance in bouncing back from a first defeat of the season away to Watford last weekend.
