The Scottish Sun claims that Rangers and Wigan have settled on a £220,000 fee for the transfer of the 24-year-old defender.
“Rob is exactly the kind of player I want to attract,” Warburton told The Daily Record. “Hopefully he’ll be in Glasgow on Monday to go through the medical and finalise the deal.
“For a defender, he’s technically excellent and at 6ft 3in has a real athletic presence. He has proved his credentials in the English Championship but most importantly is still young enough to develop and to be improved.”
Warburton has worked with Kieran before, first at Watford’s youth academy and then at Brentford on loan.
This means that the newly-appointed Rangers manager knows the kind of player he is signing, and the Gers fans should be optimistic.
Kieran joined Birmingham City on loan from Wigan in February 2015 for the remainder of the 2014-15 campaign.
In 12 appearances in the Championship for City, the former Watford man scored one goal, created two chances, had a pass accuracy of 69%, and won 31 headers, one dribble and 15 tackles.
