With a move for Nantes ace Emiliano Sala stalling, Cardiff now need to look for alternative options in attack before the end of the transfer window.
Now, TEAMtalk report that Cardiff are back in for Everton misfit Niasse, and have made an approach in order to try and secure a deal this month.
Niasse, 28, hasn't started a single Premier League game this season and appeared just five times as a substitute, totalling only 58 minutes.
The Senegalese ace has played just twice since the end of September, becoming a complete misfit at Everton as Richarlison has been converted into a striker.
A move to Cardiff could see Niasse play first-team football, and whilst Palace are also keen, Cardiff have allegedly firmed up their interest with an approach to the Toffees.
It's added that Everton boss Marco Silva is happy for Niasse to stay, which isn't surprising given that they worked together at Hull, so a Goodison Park exit is far from assured this month.
