Speaking with Sky Sports, Maguire described missing out on Southgate's squad as his career's toughest moment: "It was a really tough moment in my career; probably the toughest moment in my career to date really," he said. "To get myself in a position where all year I've worked hard to play at the end of the season, to play in these big games, these big games, these cup finals, and then go to the Euros to try and win the tournament for my country.
"I felt like I had got myself in a great position physically and mentally to go and perform at the highest level, and to face the setback that I did with the injury, was a really tough moment for me. When you see the Euros being played, you can't really go hiding from it all, but I have great friends, family and support around me and I enjoyed my holidays, even though, like I said it was a tough moment for myself mentally in my career.
"I managed to watch the games, they're such important games, especially as I've been a massive England fan throughout my life, so it was so hard not to be there."
