Silva, after a six month spell with ASM last season, remains on-loan with the Ligue 1 giants this term.
The 30 year-old told L'Equipe, "During these two years, there were some very complicated things to endure. But you have to know how to bounce back. This summer, Leicester had changed coaches (in February, Brendan Rodgers replaced Claude Puel).
"He asked me what I wanted. I told him that I did not feel very well there: with all that had happened, I associated the place with negative things. He understood. After, it took time for the clubs to agree.
"I liked Monaco. I feel very good there."
