The midfielder made his debut for the French national team in August but has been relegated back to the Under-21s due to him failing to produce the form that persuaded Les Rouge et Blanc to pay 20million euros after just one season with Sevilla.
Kondogbia isn't too worried, though, and is confident that once he fully adapts to life in the principality, he will be back to his best.
"I think I can do a lot better. I try not to be too hard on myself, but I know that I can offer a lot more," the 20-year-old said.
"In terms of the impact I make, how I'm playing, I'm usually a lot more at ease. With time, it'll get better.
"This period of adaptation, I had it when I arrived at Sevilla, so I'm not worried. I became a first-team regular and was playing well by the end of October, early November. I hope this time it'll be quicker."
