It's been a crazy few days for Manchester United youngster Jim Thwaites.
On Friday, he played the full 120 minutes in central midfield as United beat Crystal Palace at Old Trafford to reach the FA Youth Cup final.
On Saturday morning, he was on his way to London so he could be named as a substitute in the Premier League for the first time as Michael Carrick's side beat Chelsea.
Tonight he will be back in the capital as United try to beat Palace again, this time at Selhurst Park, in the Premier League Under-18 Cup.
Sitting at Carrington, alongside Under-18s skipper Dan Armer, Thwaites admitted it had been a lot to take in.
"I was delighted, over the moon, obviously, to hear the news," he explained.
"On Friday I was concentrating on the game and getting the job done there. It was later, after the game, I was told I was on the bench for the first team."
Travis Binnion, who was in charge of United's Under-21 team until he was elevated to the senior ranks following Ruben Amorim's dismissal in January, gave Thwaites the good news and travelled down with the youngster, whose family are based in Cumbria, the following morning.
"I had to tell my family and stuff like that," said Thwaites.
"I'm just trying to learn as much as possible from the pros because that's where you want to be realistically, so just grasp it all in."
Thwaites was part of the senior squad that travelled to Maynooth for a four-day training camp less than a fortnight earlier.
He and Armer were part of the group that went to Malaysia and Hong Kong at the end of last season. Both have regularly been called into the senior group for training.
"You can take bits from the first-team and even the staff will come up to you and give you little bits of advice you can focus on," said Armer.
Both players highlight skipper Bruno Fernandes as one of the most welcoming players in the seniors group.
"All of them are really good to be fair, but Bruno will take you to one side and make sure you're alright," said Thwaites. "But also, on the pitch he will encourage you and let you know that the standard here is the standard you should be aspiring to get to. But he is also helping you to get to that level."
Thwaites has been likened to David Beckham because of the way he takes free-kicks.
Armer has an uncanny resemblance to Harry Maguire in the way he runs and passes the ball.
"I've seen the comparisons," he laughs. "And they've been brought up [within the group]."
The main comparison is with Scott McTominay though. Both are born within 20 miles of each other in the north-west but chose to represent Scotland, who they qualify for through their parents.
Armer added: "You see what McTominay is doing for Scotland now and think that's just what I want to do, play at the highest level internationally."
