The Sunderland manager says signing the South Korean on a full-time basis is up to the parent club, adding that he intends to deploy him in a more attacking role in the futureSunderland manager Gus Poyet says the decision to sign Ki Sung-Yueng permanently depends on Swansea City's willingness to sell.
The South Korean midfielder joined the Stadium of Light outfit in a season-long loan deal in August and his since made 11 Premier League appearances for Poyet's charges.

"It's not in our hands at the moment," Poyet is quoted as saying by The Northern Echo.
"It's up to Swansea and not up to us."
Poyet has normally employed Ki as a defensive midfielder, but he was utilised in a more attacking role in the club's 0-0 draw with West Ham on Saturday.
And the Uruguayan believes it is a position more suited to Ki's style.
"We had a chat with Ki," he continued. "He prefers to play in front of the back four, but of course you need to work a lot defensively, and he's not that type of player.
"So we said to him that we'd give him a chance to play forward. He can pass the ball, he's not the type of player where the ball is flying over his head, it could be interesting for us if he plays there again, it could be an option for us."
