Everton have held talks with Rangers about the availability of striker Nikica Jelavic.
STV has learned that Toffees have made a formal approach for the striker as they look to bolster their attacking options ahead of this Tuesday's transfer deadline.
Discussion between the Merseyside club and Rangers took place on Sunday.
The Croatian, who did not feature in Rangers 4-0 victory over Hibernian due to illness, could now seal a move to Merseyside after catching the eye of manager David Moyes.
It is understood that Everton have funds in place should a deal for Jelavic materialise, having sold Russian winger Diniyar Bilyaletdinov to Spartak Moscow for an undisclosed fee.
The 26-year-old was recently the subject of a failed bid from West Ham while Premiership sides Liverpool and Queens Park Rangers have all been linked to the striker.
Following Rangers victory over Hibs, boss Ally McCoist said that although he was "hopeful" of keeping the marksman - who has scored 14 goals this season - he believes that his side will be able to cope should he leave.
McCoist had earlier expressed interest in signing Pawel Brozek from Turkish club Trabzonspor, but the Polish striker has joined arch rivals Celtic on loan.
Midfielder Juan Manuel Ortiz could be set to leave the club to return to Spain. Although there has been no formal contact with former club Almeria, a move could materialise before Tuesday's deadline.
