The Norwegian is very impressed with the impact the youngster has had in midfield.
The defender has been playing in holding midfield and doing a great job for Mauricio Pochettino's men.
His performances have not gone unnoticed with many a fan and pundit suggesting that Dier has been Tottenham's best, or at least most surprising, performer of the season.
One such man is a former Spurs goalkeeper. Erik Thorstvedt was with Spurs for seven years and played 97 times for Norway in his long and successful career. In fact he retired whilst at White Hart Lane after a string of back injuries.
Nowadays a football pundit in his native Norway he was speaking about Spurs yesterday on his TV show 'Matchball Mandag' and in quotes reported by Nettavisen had this to say about Dier's impact on the Tottenham first-team:
"I was dismayed at the start of the season. I thought 'what the hell will he do in midfield.'
"I may have to admit that Pochettino knew better than me and knew what he was doing.
"Dier has sealed the hole in front of the central defenders that previously were often empty because the midfielders were offensive in mindset. He is there not primarily for what he does with the ball, but for what he does without the ball. He lies there and gives a defensive balance."
There is no doubting the fact that Dier has clearly had a positive impact on the defensive aspect of Tottenham's game - an issue that needed to be addressed.
The improved form of Kyle Walker and Danny Rose has helped, along with the acquisition of Toby Alderweireld.
But the protective shield that Dier has provided has been a vital tool for Poch's men.
