Lukasz Fabianski will swap the Emirates Stadium for the Liberty Stadium.
The Polish stopper has been second choice to Wojciech Szczesny for the past couple of seasons, but the 29-year-old will move to the Liberty Stadium on a free transfer with his contract expiring this term.
Fabianski will be in for some competition in South Wales for the number one jersey with Michel Vorm and Gerhard Tremmel also likely to compete for a starting place in Garry Monk’s side next season.
Fabianski made his Arsenal debut in 2007, the first of 75 appearances for the club, and was part of this season’s FA Cup winning side as the Gunners ended their nine year wait for a trophy – with his performance in the penalty shootout in the semi-finals against Wigan Athletic a notable contribution.
It’s said that he wanted to leave the club in order to play every week.
He was quoted saying back in February: "I want to be number one in the club and in the Polish national team. I have learned a lot at London during very positive and challenging periods.
"With biggest respect to this great club, I didn't accept the extension offer as I am looking forward to a new challenge in England or abroad."
One will now wonder if the move means that Arsene Wenger will be in the market for another goalkeeper in order to provide competition for Szczesny.
