Sung-Yeung Ki has undergone surgery to cure a niggling and persistent knee problem in an attempt to return fully fit for the start of pre-season.
Swansea City's tidy 2-0 win over Stoke City at the weekend saw plenty of positive fantasy performances from the in-form side, but a trip to the Emirates next may prove difficult for them to keep up things up.
Ki Sung-yueng salvaged a point for Swansea against Sunderland by scoring against the club he played for on loan last season.
Ki Sung-Yueng is off to play for South Korea for the Asia Cup that kicks off this month, leaving a void in Swansea City's midfield.
With Arsenal and Manchester City in their next two games, it would be wise to ignore Swansea City for fantasy purposes, with the possible exception of Sung-Yueng Ki.
South Korea XI: XI: S G Kim, S Y Yun, Y G Kim, H M Son, Y Lee, J C Koo, K Y Han, S Y Ki, C Y Lee, S W Kim, J H Hong
Despite a valiant effort to get back in the match in the 2nd half, three goals conceded by South Korea in the opening 45 minutes would prove to be too many as they fall to Algeria 2-4.

On-loan midfielder Ki Sung-yueng is struggling to play any further part in Sunderland's battle for Premier League survival due to a knee injury.
After trailing 2-0 during the second half, Gus Poyet turned to his bench for Adam Johnson and Sung-Yueng Ki, and the two would link up for the Black Cats only goal, but it was not enough in a 2-1 loss.
We reported the rumors earlier that Sung-Yueng Ki could be recalled to Swansea but the deadline for him to be recalled has passed and Ki will remain with Sunderland for the rest of the season.
Swansea City have insisted they could still recall Ki Sung-yueng from his loan spell at Sunderland.
Sung-Yeung Ki scored from the penalty spot after being fouled in the box by Everton's Tim Howard, and the resulting man advantage helped Sunderland secure three massive points at Goodison Park in a 0-1 shocker.
Gus Poyet will explore the possibility of turning Ki Sung-Yueng's season-long loan deal at Sunderland into a permanent transfer.
