The Spanish coach left the club 24 hours after the end of the season, which finished with the Baggies avoiding relegation from the Premier League by just one place.
The 51-year-old replaced Steve Clarke as West Brom boss in January, but managed to oversee only three wins in his 17 games in charge at The Hawthorns.
Speaking to radio station El Larguero in his native Spain, Mel said:
"I didn't want to betray my style of football. The Premier League is a wonderful experience. The organisation is fantastic. Everybody should try this.
"But English people live football in a different way; not better, just different.
"And I couldn't betray the way I understand football should be (played). They invented this game and they have their own style."
Mel also reflected on a turbulent time at the club, where striker Nicolas Anelka was sacked by the club following his anti-Semitic "quenelle" gesture, while the sale of Shane Long to Hull City on the day Mel arrived denied him the services of another front man.
He added: "I'm proud and happy because West Bromwich Albion achieved safety despite of the difficulties we went through: Anelka, important players were sold, I lost my best strikers in a week, we had a difficult calendar too."
