The Scottish Sun report that head coach Warren Joyce is ready to rescue the 27 year-old from a difficult spell at Ibrox, where he has fallen well out of favour.

O'Halloran joined Rangers for around $900,000 on a six-and-a-half year deal in February 2015, but the Glasgow-born forward dropped down the pecking order after the misdemeanour of falling to show for a development match.

He was loaned back to previous club St Johnstone at the start of last season and scored five goals in 16 games in the Scottish Premier League between August and January.

However, the former Celtic youth-teamer then committed the ultimate faux-pas, being pictured among jubilant fans of the Gers' bitter Old Firm rivals during the Scottish Cup final in May as the Hoops sealed the treble.

Melbourne City rescued another Scottish forward, Ross McCormack, from the doldrums at Aston Villa last year. McCormack rewarded them with 14 goals in 16 appearances during his five-month spell in the A-League.

England and Liverpool legend Steven Gerrard was named Rangers' new manager last month.
