Former Tottenham defender praises Manchester City's title winner.
Walker was controversially sold last summer for £50 million after nine years at the club.
He has become a Premier League title winner in his first season in Manchester, clinching the title at the weekend.
Not all fans are happy to see Walker be successful without Spurs, but club legend Roberts insists supporters should be happy for the right-back.
Commenting on Twitter, Roberts says Walker is deserving of his medal.
Got to know @kylewalker2 well while at spurs and depsite a few obvious boos at the weekend I am glad the majority realise what a good servant he has been to us and a very good playerI have a lot of time for him a real top man and wish him all the very best.Congrats again to Kyle— Graham Roberts (@GrahamRoberts4) April 16, 2018
While Tottenham fans may want to feel happy for Walker, his personal glory could be detrimental for them.
Tottenham do not want their players to suddenly think the grass is greener and start wanting to take shortcuts to try and win medals themselves.
