Sunderland have signed South Korea midfielder Ki Sung-yueng from Swansea City on a season-long loan, the Premier League clubs announced on Saturday.
Ki, 24, is Sunderland manager Paolo Di Canio's 11th acquisition of the transfer window.
He played 38 times for Swansea last season - including in their League Cup final victory over Bradford City at Wembley - after joining from Celtic for 5.5 million pounds ($8.51 million)in August 2012.
But Ki has made only three substitute appearances so far this season in the face of competition at Swansea from Jonjo Shelvey, Jose Canas and Jonathan de Guzman.
Sunderland lost 3-1 at Crystal Palace in the league on Saturday and have one point from their first three games.
