Rangers have had two six-figure offers for St Johnstone forward Michael O'Halloran rejected by the Perth club.
It is unclear if the Scottish Championship leaders will increase their bid again for the 25-year-old.
O'Halloran, who joined Saints in 2014 after leaving Bolton Wanderers, won the Premiership player of the month award for November.
The Scotland Under-21 cap has made 23 appearances this season for the Saints and scored four goals.
Glasgow-born O'Halloran played for Celtic as a youth before joining Bolton.
He failed to break into the Trotters' first team and had loan spells with Sheffield United, Carlisle United and Tranmere Rovers before switching to McDiarmid Park.
