Reports this week have suggested that Celtic are ready to enter the race to sign Genk's versatile Senegal international Kara Mbodj.
The 25-year-old, who can play at centre back or in midfield, has attracted interest from the likes of Crystal Palace, Newcastle United and West Ham United this season, but Celtic boss Ronny Deila is a noted fan of Mbodj.
Whilst Deila was managing Norwegian side Stromsgodset, Mbodj was lining up for one of their rivals, Tromso, and regularly went up against each other.
That knowledge of the powerful Mbodj is likely driving Deila's desire to bring him to Glasgow, but the decision ironically hinges on former Rangers boss Alex McLeish.
McLeish is currently managing Genk and will surely not want to lose Mbodj, who could be seen as the replacement for Victor Wanyama at Celtic.
Yet according to The Scotsman, Genk are adamant that he won't be leaving in the January transfer window, and have even slapped a £5m price tag on their star man.
"There has been interest in him but he’s under a long contract here and anyone who wants him will have to be realistic about a valuation. That means in the region of £5 million," said a 'source' cited by The Scotsman.
Celtic will want to tie up a permanent deal for John Guidetti in January, meaning that it could come down to one or the other rather than both, with Deila not having bags of money to spend on reinforcements.
