The potential new Rangers recruit is said to have impressed the Ibrox manager, Steven Gerrard.
Rangers are reportedly close to completing their sixth January signing, according to the Sun.
Three players – Jermain Defoe, Steven Davis and Andy Firth – have already arrived at Ibrox this window, with two others – Glen Kamara and Jordan Jones – having agreed pre-contract deals.
And the newspaper reports that Rangers have now been granted a work permit for the recent Light Blues trialist, Matt Polster, around a month after he first linked up with Steven Gerrard’s side.

Polster’s capture could see Jordan Rossiter leave Rangers on loan, with several clubs reportedly keen.
