Who has your club signed in the January transfer window?
Milivojevic, 25, was closely monitored by a number of clubs last summer but Olympiakos refused to accept offers for their Serbia international.
The report claims Palace manager Sam Allardyce was hopeful of completing a deal for Milivojevic.
But Hull’s interest has frustrated the former England boss’ chances to making the signing.

Zenit midfielder Mauricio (left) is supposedly free to leave the club
And Hull have also been named among a host of clubs eyeing Zenit St Petersburg midfielder Mauricio.
According to Russian outlet Tass, Zenit are in “detailed negotiations” with Mauricio over a deal to sell the 28-year-old.
Zenit believe they are close to capturing Rostov midfielder Christian Noboa and need to make room in their squad for the Ecuador international.
Noboa has six months left on his Rostov contract and the club are willing to listen to offers.
Hull, however, face a battle to sign Mauricio, with Fiorentina, Nice and Bordeaux all eyeing the Brazilian.
