Rob Kiernan
Centre-back Kiernan made the switch to Rangers in the summer of 2015 for a fee of £200,000 from English club Wigan.
The 26-year-old came in for some criticism during his debut campaign at the club despite his partnership with Danny Wilson helping the club make their way back up to the Premiership.
He was then awarded a new deal just last July, taking him up to the summer of 2018 at Ibrox.
The club’s hierarchy must now be regretting their decision with the Irishman having an even tougher time in Scotland’s top-flight and with the Scottish Sun reporting earlier in the month that English League One club MK Dons were chasing his signature, Rangers must simply try and recoup their initial spend on the defender flop.
