QPR and Wolverhampton Wanderers remain interested in signing Celtic's out-of-favour utility man, Momo Sylla, in the summer, BBC Sport understands.
Momo Sylla has played in defence, midfield and attack
Both English Championship clubs expressed an interest during the January transfer window without a transfer materialising.
But a move for the 27-year-old is more likely at the end of the season.
Sylla will have a year of his Celtic contract to run and could negotiate an early release.
The Guinea international, who has played in defence, midfield and attack with the Scottish champions, has made just 37 starts for Celtic since signing from St Johnstone for £650,000 in 2001.
He has made only nine appearances this season, mainly as a substitute, and Celtic appear willing to let him leave Glasgow.
