Speaking to ITV, Gordon said: “I was disappointed, because I believe in myself so much. I feel unstoppable, especially at that point of the season I had just had.
“I felt like no-one could defend me, no-one could deal with me over 90 minutes. I felt like I was ready to and really impress people and help the country win the trophy.
“To envision what I envisioned… to what it was, it was disappointing.”
Gordon added when questioned if he spoke with Southgate or if the manager gave an explanation for his exclusion: “Nothing, really. I didn’t ever really ask. I’m not really that type of guy. I just like to get on with what I’ve got to do.
“I believe in myself, so even from the bench I was thinking, ‘If he brings me on, I’m going to be ready, I’m going to change the game.’ But it didn’t happen.”
