Former Swansea City boss Carlos Carvalhal admits he dreams of returning to the Premier League.
The Portuguese says his ambition is to win the Premier League title.
He told Marca: "I accepted the challenge knowing that we were in the Second, we beat Arsenal and Liverpool, we had 11 games without losing ... but it was a squad with many limitations and, although I did not manage to stay, we gave it a shake.
"Coaching in the LaLiga I think it's something that one day will happen because of the linguistic, cultural, football proximity ... I like to see Betis and Barça play ... I think I could build a team that will play good football in Spain."
Carvalhal added: "My dream is to win the Premier League one day, they'll think I'm crazy, but I had the same dream when I was training in the Third and that was far from England."
