The centre-back, who missed out on the 26-man England squad for the World Cup was devastated by Tuchel’s team selection which also saw the likes of Phil Foden, Cole Palmer and Lewis Hall miss out.
Following news that he had been left out, Maguire released a statement on social media stating he was “shocked and gutted by the decision” as he is now forced to watch from home.
Tuchel chat was awkward
Speaking on Gary Lineker's Rest is Football World Cup podcast, Maguire revealed how Tuchel broke the news to him as he admits he let his disappointment known immediately.
"He FaceTimed everyone. It was quite an awkward call.
"I received a text saying can I speak to you about 4pm. It is quite a unique way of doing it and it must be quite hard because he can see everyone's reactions.
"I said straightaway I was really disappointed. I thought I did enough to be in the squad and thought I could have helped and had a part to play on and off the pitch.
"He said he can't give me an excuse but he had gone with the four lads who got him through the autumn.
"It was tough to take. I did think I would be in the squad after being selected for the March camp under him for the first time. I did really well in both games and then went back to Manchester United and finished the season really strongly."
Maguire won't back down
Speaking more on his international future, the 33 year old said he is not giving up anytime soon despite turning 35 by the time the next Euros comes along.
"I don't think I would retire from England. I still feel I have something to offer. There will be a time and a place where I don't deserve to get picked but I probably still wouldn't come out and retire.
"If I got one more cap it would be worth it."
