The winger also detailed his recent experiences training under first-team coach Jose Mourinho at Benfica, where a clip of their interaction on the training ground went viral in late April.
"Life in Portugal has been good; it's been a very good experience," said Umeh.
Umeh revealed the lighthearted nature of his conversation with the legendary manager, who routinely monitors and rewards academy prospects.
"In that clip, he was actually asking if my Portuguese was good! I was laughing, saying it's alright.
He's one of the best managers and coaches in the world, so to have him giving me advice was really, really good," said Umeh.
The modern winger outlined his core strengths on the pitch, highlighting his physical readiness, quickness, and preference for one-on-one situations.
"There are a lot of players, and everyone tries to push the person in front of them.
Moving at 16 by myself was a bit of a change, leaving home to live alone in a new country with a new language, but I just had to let my football do the talking.
It opened new doors for me," said Umeh.
Umeh emphasized that training alongside Liverpool goalkeeper Caoimhín Kelleher, a fellow Ringmahon Rangers graduate, represents a personal milestone.
"It's definitely something we still dream about.
In two or three years' time, to have Jaden Umeh on the left and Franco Umeh on the right for Ireland, that would be something special," said Umeh.
The teenager concluded by reflecting on a long-standing childhood ambition shared with his older brother Franco, who currently plays for Portsmouth.
"Growing up, we always had Ireland jerseys with our names on the back.
I had a 'J' in front of mine and he just had 'Umeh', because he's the older brother!
It's a dream for our family, for my Mum and Dad. To see that happen would be unbelievable," said Umeh.
