The Spurs right-back has impressed at the Euros this summer.
England's Kyle Walker shoots
The Spurs full-back has suffered with inconsistency over the years but hit top form towards the back end of last season and has carried that over onto the international stage with England.
England's Kyle Walker in action
“Kyle is full of confidence and that’s important,” said King. “He was named Man of the Match against Portugal in the final friendly and that has got him the starting place in the tournament.
“He had that chance, he took it and he’s gone from strength to strength. He’s had his best season for the Club and that has carried onto the international scene now.”
Walker has been one of the stand-out performers of Euro 2016, with his powerful running and aggressive defending ensuring he offers plenty at both ends of the pitch.

The 26-year old has always been renowned for his attacking ability but his game has become more well-rounded in recent times and he now looks to be the complete package.
“You have to remember when he had that unbelievable breakthrough season in 2011-12 (when Kyle was named PFA Young Player of the Year) he was still very young and still had a lot of learning to do… He’s done that,” added King.
“He’s always been great going forward and there is no stopping him now. He has the right balance of attacking and being a top-class defender now.”

The emergence of Walker and Danny Rose as England’s first-choice full-backs is great news for Spurs ahead of next season, with the pair’s confidence likely to be sky high after strong showings at the Euros.
Complimenting those two with Belgian centre-back duo Toby Alderweireld and Jan Vertonghen, and France captain Hugo Lloris and it’s not hard to see why the Lilywhites boasted the best defensive record in the Premier League last season.
Add the newly-established England anchor Eric Dier and new signing Victor Wanyama to the mix, and Spurs sure look like being a tough nut to crack.
