Celtic accepted an offer for Ki with manager Neil Lennon describing the fee of around £6m as "good business".

"It will be unfortunate to lose a talented player, but that's been our strategy at the club now for the last two or three years," added Lennon.

Celtic assistant manager Johan Mjallby said on Monday: "He is keen to move on. There have been a few clubs interested in him.
"He is a quality player, but on the other hand he is keen to move on, so the club needs to do something.
"He was away at the Olympics for a period of time, but we will be sorry to see him go."
The Swede also said he was not convinced Celtic would have to replace the 47-times capped player, while Lennon was unsure if any funds would be made available from the potential sale.
"He has not really been a part of the season so far so we have shown that we can live without him, but on the other hand it would be nice to get someone else in if he goes away," added Mjallby.
"If quality players leave the club, you want to freshen things up and have competition.
"But, even with Ki here, we would like to see some other faces."
