Gana moved to Villa from Lille in the summer transfer window, and he has played a prominent role for the Midlands side since joining.
The Senegalese international has already made 25 appearances for the Claret and Blues, and he admits the transitional process has been a tough one.
“I'm finding the Premier League exciting but also very hard because of the results we've had this season,” he said.
“But I'm happy to be here and to play for Aston Villa. It was very easy settling in here because the weather is not much different to Lille and the city of Birmingham is very nice.
“There were a lot of people here who helped me out to make the integration very smooth. I will continue to try and do my best for this club because it is a huge club that shouldn't be on the bottom of the table.”
Gana has shown some potential with his performances in the centre of midfield, with his energy and power catching the eye.
Although the 26-year-old has made some errors, his recent displays under Remi Garde’s stewardship have been impressive.
Garde’s Villa side seem to have made improvements recently, and they have become far tougher to beat.
Although Villa are still eight points adrift in the relegation zone, they did win their last match against Norwich City, to move slightly closer to safety and increase optimism levels slightly at Villa Park.
