Atletico Madrid fullback Filipe Luis insists he has no regrets over his year with Chelsea.
The Brazil international never secured first-choice status at Stamford Bridge before returning to Atletico.
"I am happier in Spain," he said. "I do not regret going to Chelsea, I do not think I made a bad choice at the time, it was a short stay of only a year, but it was good to win the Premier League.
"The adaptation was not what I wanted, and I was never a first-choice.
"Atlético were always interested in my return and I really have a lot of attachment to the team, but I wanted to live that experience, the opportunity to play that competition that they say is the best.
"It was a good experience and I faced very fast and strong players."
