Ki Sung-Yueng's father has revealed the details behind his son's spat with Swansea boss Michael Laudrup which led to the player's initial - and continued - loan to Sunderland.
Speaking in Korea, he explained how an argument over injury grew into mutual distrust and ill-feeling, culminating in Ki's departure.
The contract made by both Ki and Swansea includes a clause that the player will be guaranteed to play the least 20 games as a starter which Ki himself wanted and included.
The Chelsea game was his 20th game playing as a starter, and this is the game he resulted in heavy injury on his thigh. Ki told Laudrup that he would like to treat his injury in the Korean National Medical Centre as he precisely judged the facilities there are much better than those at the club.
However, Laudrup mistakenly believed that Ki was trying to make a lame excuse after his 20th game of him being starter so as to slack off as much as he can. That inconsiderate thought of Laudrup led him to him disliking Ki.
Laudrup later approved Ki of his suggestion and let him go get treated in Korea, and Ki believed Laudrup fully understood what he told him and took it to his heart with gratitude.
When Ki came back, Laudrup brought in new players at his position and started ignoring him and excluding him from game to game. and this continued for a while.
Ki realised something was wrong, and he asked Laudrup why he can't play as a regular starter. Laudrup said to Ki that he isn't trustworthy as a professional footballer and avoided Ki in any direct conversations.
Michael Laudrup's own future at Swansea is now reportedly being called into question, with many newspapers reporting the Dane will leave in the summer after a poor campaign so far. Whether that effects Ki's own future is unknown.
The reason why Swansea didn't get Ki back [earlier this month when they had an opinion in the loan agreement to recall him] was due to Laudrup's own objection toward the plan, yet the club, unlike Laudrup, wants to keep Ki in a long run.
Swansea offered an extension in Ki's contract with better clauses but Ki was obviously worried about Laudrup's dislike of him. So Ki is being cautious.
Regardless of Laudrup's future, however, with just one year left on his Swansea contract this summer Sunderland will be in a strong position to sign him should they manage to stay up.
It's quite obvious how much Ki is enjoying his spell on Wearside under Gus Poyet. Any contract extension at the Liberty Stadium would presumably only really be an option after he has waited to see what any new manager brings and by then the Swans would be risking losing him for nothing.
Anyway, let's see if we can ensure survival first before worrying too much about this kind of stuff. It is just one side of the story, after all. Interesting, nonetheless.
