Celtic have confirmed South Korea midfielder Ki Sung-yueng is in talks to leave the club - as revealed by The National yesterday.
The midfielder is closing in on a transfer to Swansea City, and has not travelled with the Ceitic squad to Sweden for their Champions League qualifying match against Helsingborgs this week.
"He is keen to move on and the club is in discussion with another club so we have to wait and see what happens," Mjallby said.
"There have been a few clubs interested in him but I know for sure there has been one bid for him and I think maybe one or two other bids.
"He is a quality player but on the other hand he is keen to move on so the club needs to do something."
AC Milan forward Antonio Cassano and Inter Milan striker Giampaolo Pazzini are to discuss personal terms with over a surprise swap deal.
Milan chief executive Adriano Galliani confirmed the possible exchange between the rival clubs after the Rossoneri's 3-2 defeat by Serie A champions Juventus in the Berlusconi Trophy friendly on Sunday.
The Rossoneri are looking for a replacement for Zlatan Ibrahimovic following his move to PSG last month, with Pazzini looking to get his career back on track following a lackluster season last term.

Manchester United have been linked with a shock move for Dutch defender Alexander Buttner - after the player claimed he was about to seal a 'dream' move to Old Trafford.
The 23-year-old, who featured in Holland's provisional Euro 2012 squad, had been a transfer target for a number of English Premier League sides - with a deal with Southampton collapsing earlier this summer.
But the Vitesse Arnhem left-back told a Dutch TV station he was about to complete a £4m (Dh22.7m) move to Manchester United.
"This is really a dream come true," he said.
"It was all arranged very quickly and of course I am very delighted. Happily everything is coming to an end."

The Dane did so on Saturday on a one-month loan deal, playing the full 90 minutes of Portsmouth's 1-1 npower League One draw with Bournemouth.

"Kieran came to see me a while ago in the last transfer window," he said.
