Hall suffered a broken foot in the lead-up, which not only ruled him out of the Wembley clash with Liverpool, but he also couldn't attend the game on the day.
Now back with England U21s, Hall recalled: “It was the worst part of my career so far. The cup final was incredibly hard to take.
“Even now — although we won and I’ve got my medal and everything — it still hurts quite a lot seeing that and not being able to be there.
“Not so much not being able to play, but I’d had my surgery five days beforehand, so I wasn’t able to get to the game and celebrate with the team, which was difficult.”
Hall continued: “I spent a lot of time with my family back home, who are probably the people that I’d open up to the most.
“But at the club, we have a psychologist who I used to speak to every week.
“I used to speak to the coaching staff fairly regularly and the players.
“I tried to keep myself having breakfast and lunch and do everything I could with them to keep myself part of the team.
“Everyone was so good with me and they knew how much it was upsetting to me to miss the cup final. It’s made me mentally a lot stronger. It’s all just part of the process.
“Now I’m just enjoying every moment and never take anything for granted these days.”
