Hector Bellerin believes the higher level of professionalism in England's youth set-up made his move from Barcelona to Arsenal worthwhile.
Bellerin started his career in Barca's La Masia academy before heading to London at the age of 16 to continue his development.
And the 22-year-old believes the parallels between the youth and senior game in England make it a better place to learn about every facet of the game than Spain.
"Everything is much more professional in England, at an early age," Bellerin told Arsenal Player.
"I remember doing hydration tests, body fat tests, mobility tests, looking at the data after the games, during training sessions, everything.
"When I was at Barcelona it was all about the football. It was a completely different mentality. Also the league was way different in Spain. You play against the other teams in your region. For us that meant Catalonia and we only had a couple of games each season that were difficult for us. That was against Espanyol, the other top-division team in the city.
"But here playing for Arsenal we used to play all around England against other Premier League teams. So the difference was really big in loads of senses.
"I also think in England you have to travel a lot and spend nights in hotels from an early age. That gives you a really good taste of what it is like as a pro footballer.
"You learn early on that it can be a lonely life. Of course you are with your team-mates, but you find out early that there a lot of things that you cannot do, and there are a lot of family events that you cannot attend.
"You need to realise that from a young age and the fact you have to travel so much to play against teams far from home, it gives you an early taste of how it is at the top level."
