The club-record £40million arrival of the midfield maestro, who impressed in his six-month loan spell at the King Power Stadium last season, was seen as a massive coup for the Foxes.
"During the transfer window, I was happy of the interest of certain big clubs," Tielemans said.
"I needed to make a choice for my young career and I think it was the right one. To arrive off the back of a €45m transfer doesn't change anything.
"They already knew me at Leicester. My loan spell went very good. I wanted to continue playing in this club."
