Swansea City boss Garry Monk says it was the right time for Ki Sung-yueng to undergo knee surgery.

The influential midfielder has had a limited role in recent weeks after an impressive campaign and Swansea revealed before Sunday's 4-2 Barclays Premier League home defeat to Manchester City that he had undergone minor knee surgery.

"All players carry niggles and you have to decide whether you can manage it or it needs to be dealt with immediately," Monk said.

"Ki has been fantastic and you want someone who has done that well to be part of it to the end of the season, but you do not want to take any risks."
