Alex Rae reckons Rangers transfer of the summer is key figure who won't be near Michael Beale's team sheet

Alex Rae believes new chief executive James Bisgrove could be the biggest summer signing for Rangers on the day he officially took over from Stewart Robertson.

Former Ibrox midfielder Rae has been impressed by the work done by Bisgrove in helping Michael Beale carry out a complete overhaul of the squad. Stalwarts like Allan McGregor, Scott Arfield, Alfredo Morelos and Ryan Kent all left along with Filip Helander and Antonio Colak, who was sold to Parma, while Malik Tillman returned to Bayern Munich.
