Ki Sung-yueng is believed to be looking for a new club as he is growing tired of warming the bench for Swansea City in the English Premier League, the team he joined after parting ways with Scottish powerhouse Celtic in August last year.

He was apparently frustrated once again at not being part of Swansea's 5-1 demolition of Romania's Petrolul Ploiesti during their recent UEFA Champions League playoff game.

WalesOnline reported that Ki had "slipped down the pecking order" after coach Michael Laudrup acquired Jonjo Shelvey and José Cañas this summer. It added that Ki may be heading to rival EPL outfit Sunderland on a one-year loan deal, where he would join compatriot Ji Dong-won.

However, with only a few days remaining before the summer transfer window closes, Ki must move fast if he hopes to spend a more productive season in either the EPL or German Bundesliga.

Ki played 38 games for Swansea last season -- 29 in the Premier League, two in the FA Cup and seven in the League Cup. After he joined the club for 6 million pounds, the largest transfer fee ever recorded for a Korean player, he soon established himself as a defensive midfielder who posed a constant threat with his free kicks and corner kicks.

But after Laudrup guided the club to win the League Cup last season, he announced that he would be making a significant overhaul, and subsequently brought in new midfielders including Shelvey from Liverpool and Cañas from Real Betis.

Ki has been in the doghouse since the start of the season. He was brought on to replace Cañas in the 77th minute of the club's Premier League opener against Manchester United on Aug. 18, and reportedly had a falling out with the coach in the process.

In an interview with British media on the same day, the coach said that Ki must fight to secure his place in the midfield amid fierce competition.
