The Gunners managed to win 2-1 against Aston Villa at the Emirates and are sitting comfortably at the top of the Premier League table.
Ramsdale who joined the club one season ago believes the fans had a change in the mood fully backing the squad.
He claims that now Emirates can be a really hard place for visiting teams.
“I think [calling it] a fortress, it is quite early on, but the fans have been unbelievable,” said Ramsdale.
“[William] Saliba scores an own-goal last week and they started singing his name. Gabi made a mistake against Fulham and the fans were unbelievable. It’s the loudest I have heard it.
“Obviously, it helps that we are winning on the pitch, but it’s in the times of struggle within the game that they (the fans) are coming to our aid and helping us. And it really does lift us.
“Hopefully, we can carry on winning these games at home and make it a fortress, as you were talking about. But, for now, it’s definitely helping us so much.”
