Dimitri Payet insists he does not have to justify his behaviour after a bitter departure to Marseille from West Ham.
The Hammers lashed out at the 29-year-old as he was announced by the French Ligue 1 club on Sunday, accusing him of a lack of respect.
Payet admits he began his "stand-off" with West Ham a long time ago but insists he was unhappy in England and missed France.
"[This move] is what I wanted. It was clear from the start," Payet said, who was forced to pay back his January wages, according to Sky sources.
"I didn't feel very good over there. I wanted to be part of this project that is just getting started. It came at a time when I missed France.
"It was drawn out because I started my stand-off with West Ham a long time ago. Slaven Bilic had his view. I spoke to him. I don't want to talk about this at the moment, but I don't have to justify my behaviour.
"I needed to come back to France to Marseille - it was a personal choice. I'm very happy. My main motivation is to play football. If I was playing for money, I'd be in another country.
"If [the move] hadn't gone through I would have lived with it. Thanks to all the staff for doing what was needed."
