There's a really great article about Szobo on the following link: https://theathletic.com/2223536/2020/11/27/dominik-szoboszlai-profile-analysis-arsenal/
You actually gotta pay to read the whole thing but I'm going to copy-paste the parts where Jesse talks about Dominik:
“Certainly his greatest gift is his right foot, he can put the ball where he wants to,” Jesse Marsch, his Salzburg head coach, tells The Athletic. “But he can run all day and he’s fast, and what’s interesting is when you have a player that’s so gifted with his right foot, what I try to do is still not let him just rely on what he can do with his right foot but also to use his athleticism to be aggressive with and without the ball. And certainly running off the ball to be dangerous.
“Even last night (a 3-1 loss away to Bayern Munich in the Champions League on Wednesday) he got himself in a few dangerous spots, he should score a goal in the first half, but he’s running more in the deep, he’s being more aggressive to find ways to score goals other than just getting the ball on his right foot. That, for me, is important for him.”
“I describe him as a modern-day David Beckham,” Marsch says. “Beckham had a real ability to hook a ball and he could also chop it when he needed to, but Szoboszlai can hit the ball a lot of different ways too, and he’s got power. He can really hit the ball. He can do these things with his right foot but can also play a little more intensively and he can work harder against the ball and he can be a threat in the box still.
“He’s very fit; so whatever the physical demands you put on him, he can meet those demands because he’s fit, he’s strong, he’s fast, he’s athletic.”
So, just how good can Szoboszlai be?
“It will come down to his determination to not just want to be a passer,” says Marsch, “not just want to have the ball on his right foot and try to score goals and make passes that way. For me, based on how I think about football, it will be about his commitment to play intensively, to run, to be difficult to keep track of in a game for defenders; (when his team is) in possession, not just what he does with the ball but what he’s doing off the ball.
“The more he can tilt himself to being active and intensive and sprinting, he has potential to be one of the top No 10s in the world, there’s no question. The combination of his vision, his technical ability, his athletic ability and his personality means there aren’t many players that can dominate games from that position the way that he can.
“If you watched him play for Hungary in the last international window, he was dominant. Dominant. Against Serbia (in a Nations League game three days after his Iceland heroics), he was easily the best player on the pitch. And there are incredible players for both teams. I believe he was so determined to get to the Euros because he knows this can be a big stage for him to showcase himself.
“We use him usually as a left-sided No 10, but he can play as a middle 10, he can play as a right 10 and he can play as a No 8. When I first came here, I give him a hard time about this. We did a TV interview and the interviewer asked him, ‘Are you an 8 or a 10?’, and he said he was an 8, and I said to him, ‘Are you crazy? You’re a 10’.
“Hungary used him last game (against Serbia) as a second striker, like a nine and a half, almost. This is a little bit of trying to change his mindset a little bit. Not just to be a passer but to be a goalscorer. Normally he operates a little bit between the lines, and then we still try to demand of him to run in the deep spaces so he can be a threat in the box.”
“Without the ball, we want him in our pressing schemes to be one of the first to go out and put pressure, but he’s pretty tall (6ft 1in/186cm) and so when he gets close to defenders to close down the space and win balls it’s not so easy for him to slow down and he’s not the most agile guy,” Marsch explains.
“But he has the ability to be explosive against the ball,” Marsch continues, “to put pressure on the opponent, and I’m challenging him to win more balls. He’s got a lot better since I started working with him.”
“You have to understand, Dominik is the hope of Hungarian football. He’s the next Puskas. So, I understand the responsibility he has to his national team and I don’t want to deprive him of the opportunity to help his national team emerge and be successful. Not all managers in Europe respect the national team situation, but from working with the (US) national team I’ve seen just so many players blossom into superstars because of the pride they have in representing their country. That’s been a big reason why we haven’t always played him 90 minutes.”
“He’s awesome,” Marsch says. “He’s got a smile on his face, he comes with energy. He had a reputation for being a little bit arrogant when I first came, when he was really young, but honestly, I haven’t seen that at all. He works hard, he cares about the team, he’s a good guy in the group. He speaks Hungarian, he speaks German, he speaks English. He’s also very close with Erling Haaland, and the two of them really enjoyed playing with each other, spending time with each other, and a lot of Erling’s energy, enthusiasm, determination and humbleness also wore off on Dominik in a really good way.
“I love his personality because he wants to learn, he wants to work hard, he wants to improve, he wants to be the best. We played him every game but one last season, when he was 18 and 19, in the Champions League because I could see he wasn’t afraid of the moments. He wanted to be in those moments. That’s the special personality he has.”
