Dier, who started the season strong under Jose Mourinho, decreased his level significantly in 2021, therefore Southgate decided not to take him.
Instead, the 50-year-old chose to select John Stones, Harry Maguire, Tyrone Mings, Conor Coady, Ben White and Ben Godfrey as the six central defenders in the provisional 33-man England squad.
Gareth Southgate revealed that he opted to name a provisional 33-man England squad as there are "a lot of unknowns" behind his final Euro 2020 squad selection.
Tottenham finished the Premier League season seventh, qualifying for the newly-formed UEFA Europe Conference League. As they made their way to Europe, Spurs conceded 45 goals in the English competition.
Dier started 28 of Tottenham’s 38 Premier League matches this season.
Southgate on Dier
The England manager spoke about the Dier situation, and told Jonathan Veal that he has not been to his best this season.
Southgate on Dier omission: “He is a man who I have tremendous respect for and he has been a key player in our biggest moments. I just think his season has not been strong enough to be in the squad and that's difficult because I know how much he brings to the group." #THFC— Jonathan Veal (@jonathandveal83) May 25, 2021
“He is a man who I have tremendous respect for and he has been a key player in our biggest moments. I just think his season has not been strong enough to be in the squad and that’s difficult because I know how much he brings to the group.”
Since Eric Dier just missed out, Harry Kane will be the lone-Spurs player in the England squad this summer.
This season for Spurs, Kane registered 50 goal involvements in 49 appearances across all competitions. He also became only the third player in Premier League history to finish with the most goals and the most assists in a single season.
