According to the Daily Mail, Celtic remain interested in signing Genk utility man Kara Mbodj - if Virgil van Dijk leaves the clubs this summer.
The Bhoys have already snapped up one defender this summer, signing Manchester City defender Dedryck Boyata as a replacement for loanee Jason Denayer.
Now though, manager Ronny Deila needs to consider other centre backs with interest building in Celtic star van Dijk; The Daily Mail believe that Arsenal, Everton, Southampton and Sunderland are pursuing the Dutchman, who has a £10m valuation.
With that in mind, the Daily Mail now report that Celtic are considering a move for Senegal international Mbodj, who can play in central midfield or defensive midfield.
The 25-year-old will be familiar to Deila having played for Tromso during Deila's time as Stromsgodset manager, but the Bhoys aren't the only team chasing him.
The Sun reported over the weekend that West Ham United are also interested in a £4m deal for Mbodj, but has encountered work permit problems, causing them to consider other targets.
Celtic or West Ham?
Mbodj is clearly in demand this summer, and could have a big decision to make if both Celtic and West Ham make bids to sign him.
A move to follow his international team-mate Cheikhou Kouyate from Belgium to West Ham could be appealing, with Premier League football a rare opportunity for many players.
Yet at Celtic, Mbodj would have the chance to play in the Champions League this summer, and possibly beyond if the Bhoys make it through the qualifiers.
Celtic appear to have been tracking Mbodj for some time, with The Scotsman reporting their interest back in December. Deila knows all about the player from his time in Norway, and with first-team football more likely in Scotland, he could well choose a move to Glasgow over East London.
