He told BT Sport: "Yeah, it's crazy how the two players especially, Alex [Zinchenko] and Gabby Jesus, they've just brought something different. The only way I can describe it is a winning mentality. Just wanting to win every time and they've been doing it with us every day so it's lifted the training."
The 24-year-old continued by stating that the Gunners' other new recruits have also made an impact on the training ground. Among those is Matt Turner, the new no.2 goalkeeper in London, whom Ramsdale has given a new nickname.
"Especially in with the goalkeepers, we've got the lad Mat Turner from America, he's like Tigger," the England goalkeeper said.
"It's like a classic American almost where you always want to do everything. He wants to say yes to everything and it's great because there's days where you're a bit tired and when you've got him who's new to the club, it picks you up."
