Despite being mostly ignored during the group stage, Palmer remains optimistic.
"I'm still full of belief," Palmer stated confidently. "After the season I've had, I don't see any reason why I should be down. So I will just try and stay positive and when I get on the pitch, try to make an impact."
The circumstances of Palmer's introduction were challenging, with England finding it difficult to penetrate Slovenia's defence. However, the 21-year-old midfielder was undeterred. "I just tried to play my game when I went on and I think I did that," he explained. "I tried to create chances and be positive. There are great players everywhere in the team, so I'm just supporting whoever is on the pitch [when substitute] and when I get my chance I need to try and show what I can do."
