Andre Gray in action with Rangers' Niko Kranjcar
Rangers will take on Hamilton at home in the Scottish Premiership on Saturday afternoon.
The Gers will head into the game as favourites and will fancy their chances of a comfortable victory.
Former Celtic striker Walker has backed Mark Warburton’s side to pick up all three points from the encounter at Ibrox.
The former Scotland international believes that Rangers will win the Scottish Premiership clash 3-1.
Walker has also stated that Rangers summer signing Niko Kranjcar will be the key player in the match.
“He has the ability to light up any game with his intelligence and passing,” Walker told Sky Sports about Kranjcar.
Rangers won the Scottish Championship title with ease last season and will feature in the Scottish Premiership during the 2016-17 campaign.
The Gers have been quite busy in the summer transfer window so far, signing Joey Barton, Kranjcar, Jordan Rossiter and Matt Gilks among others.
