Aleix Vidal has described his transfer from Sevilla to Barcelona as "the most important day of my life" after completing his Camp Nou return on Monday.
Vidal, 25, who plays on the right wing, is unable to play for Barcelona until they complete a FIFA-imposed transfer ban in January 2016.
Barca announced the signing a day after winning the Champions League on Saturday, completing a treble of trophies along with the Spanish league and Copa del Rey this season.
Vidal impressed for Europa League winners Sevilla this season after joining from Almeria last summer, and last month earned his first call-up to Vicente Del Bosque's Spain squad.
Vidal -- who played for Barca's under-14 B team during the 2001-02 season as well as spending three years at Real Madrid -- signed a five-year contract with the Blaugrana after completing his medical on Monday, and was delighted to confirm his return to Catalonia.
"Apart from the day my daughter was born, this is the most special day of my life," he told reporters at the Camp Nou on Monday. "I went through a lot to get here and I'm living a dream.
"I always try to give my best. There's no better way to learn than by playing with these teammates.
"I feel that I've come home -- it's the best thing to begin a new winning cycle. At the end of the season we were all aware that the move could take place. I was with the national team and the whole process moved along very quickly.
"At the end of the day, each player has to move around to progress. This has happened to me and I hope this will be my last team.
"From my village team, to my time at Espanyol... I've played for so many teams that if I started to name them all, we'd run out of time."
Despite having to wait next January for his Barca debut, Vidal is confident he can use the time to integrate into Luis Enrique's squad and develop as a player.
"I'm coming here to find my niche," he said. "When I was informed that the move was going to go through, I never saw it as a major issue to not be able to play until January.
"This will give me time to improve on areas of my game. For me the important thing is being here and being able to grow. The sanction is a hindrance but I will be able to feature in preseason friendlies."
The player also seemed to confirm that Luis Enrique will still be at Barca next season, saying: "I've spoken with him as it's my understanding that he will be the coach for next season."
The signing of an attacking full-back could spell the end of Dani Alves' Camp Nou career with the Brazilian expressing a desire to play at AC Milan, but Vidal is ready to battle the Barca veteran for a starting role if he stays.
"I've come to try and secure a place in the team -- I'm going to work on improving and then be available for the coach when he needs me," he continued. "I've spent some time playing as a wing back.
"Competition is key to improve. If [Alves] stays I'd be delighted, it would be healthy competition for a position."
Having lifted the Europa League with Sevilla this year, the 25-year-old is targeting more silverware at the Camp Nou after watching Barca celebrate a historic second Treble.
"If we can't add any more titles to the ones we've won this year, I hope to at least repeat it," he added. "Its important to get along with all players -- it's visible to see that Messi is key in the union between all players.
"It's easy lining up alongside the best in the world but it does require work too."
Vidal played 31 La Liga games last season, scoring four goals in 22 starts at both right-back and as a right winger.
The player proved his versatility by also playing in a central role for Sevilla's successful Europa League campaign.
