Jordi Alba marvelled at the maturity of young Barcelona team-mates Pedri and Gavi because he was playing at a significantly lower level at their age.
Gavi became the youngest player to make a senior appearance for Spain when he featured in their Nations League semi-final win over Italy last October aged 17 years and 62 days.
Pedri, meanwhile, started all six of La Roja's games at Euro 2020 and was named Young Player of the Tournament. He only turned 19 last November.
When he was 18, Alba was playing for Cornella in a regional league in Catalonia. He did not make his Spain debut until he was 22, two years after his first top-flight appearance.
"They are very mature for their age. When I was their age, I was lucky that experienced people helped me adapt, whether it was to the national team, Valencia or Barcelona. I try to do the same," Alba told a news conference when asked about Pedri and Gavi.
"We are lucky that many high-level players have come from Barcelona and that they are Spanish.
"At their age, I was playing at Cornella and they are playing European Championships and the World Cup. It's wonderful to watch them play."
Alba will captain Spain when they take on Albania in a friendly at RCDE Stadium in Cornella de Llobregat on the outskirts of Barcelona. It will be La Roja's first match in Catalonia since 2004.
"I expect a spectacular atmosphere, like in all the cities in Spain we visit," said Alba.
"We haven't seen the national team in Barcelona for a long time. I'll be able to enjoy it with my people. Hopefully the party moves onto the pitch and we'll achieve our goal of winning the game."
Spain do not have any members of their World Cup-winning side from 2010 in the squad during this international break, but Alba has no doubts about the ability they possess.
"They talked about it during the European Championship and we did well because there are very young people but with experience, and with the ability to play a World Cup," said Alba.
"People are leaving the national team due to their age and young people arrive. The work of the coach and his staff in that aspect has been spectacular.
"Whoever comes into the national team will respond, will do very well. Unfortunately, the European and world champions are retiring and those who come in will do very well."
