The Iceland star has hailed his old Tottenham Hotspur pal.
Quoted by The Belfast Telegraph, Gylfi Sigurdsson has admitted that former Tottenham Hotspur team-mate Harry Kane is a "fantastic" guy as Iceland prepare to face England in a last-16 clash at Euro 2016 on Monday.
The 26-year-old playmaker will meet a couple of his old Spurs colleagues in the competition next week, along with Kyle Walker and Danny Rose, but he reserved special praise for Kane.
Since Sigurdsson left Tottenham, the 22-year-old marksman has gone on to establish himself as one of the world's most prolific strikers, netting 25 Premier League goals last season to win the division's Golden Boot ahead of Jamie Vardy and Sergio Aguero.
That goal-laden campaign came on the back of scoring 31 times in all competitions during his breakthrough season at White Hart Lane, and Sigurdsson, who left White Hart Lane in 2014, says he's delighted for his old mate.
"He was very focused on what he wanted," Sigurdsson, now at Swansea City, said via The Belfast Telegraph. "He's a humble guy, very down to earth and really likes his football.
"I think that's what got him though in the end. Of course he didn't get his chance until a few years ago.
"But he hit the ground running and scored many goals in his first full season, and more in the second. He is a fantastic guy.
"It is hard to judge if a young player is going to become that big when they get their chance, but he's done incredibly well."
Kane is brilliant but he does not look the same player for England this summer as he was for Tottenham over the past two years or so.
He is yet to open his account in the competition and was dropped for the Three Lions last game - a 0-0 draw with Slovakia. It remains to be seen if he starts against Iceland.
