Madueke made a controversial move from Chelsea to Arsenal last summer.
"The team has been great. Of course we're flying. It's not just a team of great and talented players," he told The Dispatch podcast. "It's a team full of good people. And I think the culture around here is probably the best I've seen.
"And yeah, in terms of the supporters, it was a bit dicey at the start on social media and stuff before I came to the club. But when I've been in the stadium, I haven't felt like the fans (have been criticising me).
"Obviously I play on the side down the pitch so I can hear them and they push me on throughout the game. Whenever I get the ball I hear them.
"God willing that continues because it gives me a big. big boost.
"I always love playing at the Emirates. I always look forward to the next game when I'm back there. The fans have been amazing and I really appreciate how they've handled everything."
