Barry Ferguson has said Rangers' move to sign goalkeeper Allan McGregor is a "no-brainer" and the player would be a perfect signing for the club.

Rangers are in advanced talks with McGregor, who is out of contract with Hull City at the end of the season and he could have a second spell at Ibrox if terms are agreed.

Though a fan of current number one Wes Foderingham, Ferguson told STV that McGregor's knowledge of the club would see him become a key figure in the Rangers squad if a move was completed.
