Speaking on talkSPORT, Dyer said: "We went to the final all of us and it was very emotional. It’s mad watching it with families, it's very intense following the team around for six weeks.
"It’s not a glamorous lifestyle. They’re sitting on coaches for three hours and it hasn’t been the most exciting football either. Some of the families are there and some of their sons are not getting enough game time so there’s a little bit of friction there.
"Gareth Southgate did seem to stay with the same team so some people didn’t get any minutes. At least J [Bowen] got some earlier minutes. It’s very frustrating to sit on the bench and you can’t get any minutes. There’s nothing you can do about it so you take it on the chin, you learn from it. Hopefully whoever comes in [next manager] fancies Jarrod again and he gets to go again at the World Cup."
