The former Intercontinental champion and current SmackDown co-commentator is a massive football fan and has been watching the Three Lions closely in Germany.
Speaking exclusively to DAZN, thanks to AceOdds, Barrett shared his concerns over Gareth Southgate's men and their current form, comparing the side to the 2016 squad.
"I'd say I'm really concerned.The first few games for us have been hopeless," Barrett said.
"In the Serbia game, we should have got one point. In the Denmark game, we should have lost. We do not deserve to be in this position. And the results have flattered England, which is insane when you look at our personnel.
"And the thing that really worries me is that the game leading into this, we also lost to Iceland in our final friendly. All I can think is back to 2016 with Roy Hodgson in that European championship. I remember specifically the friendly games leading up to the tournament, we were horrible in every game.
"And then the tournament happened and we continued being horrible. The problems that we were having in the team not clicking and not connecting were exactly the same in 2016 as they are today. And these things don't miraculously change overnight."
England had been touted as potential winners before the tournament, alongside France, and while Barrett says he hasn't given up hope completely on a triumph in Germany, big changes need to be made.
Adding: "Okay, I'm not going to write everything off yet, but the way they're playing gives me absolutely zero faith that this will be fixed. And I think there needs to be a significant change either in personnel or tactically and I just don't know if Gareth Southgate is capable of doing that.
"Similar to how Roy Hodgson was not capable in 2016, he didn't know how to fix the problems, I have the same fear with Gareth Southgate. I'm still supporting the team. I hope they do well, but I am very nervous about England. I personally at this point cannot see us winning it unless something major changes and fingers crossed it does."
