The midfielder moved to the Gunners on transfer deadline day earlier this month from Atletico Madrid after Arsenal met his £45million release clause.
Arsenal have scouted Partey for years and had been chasing him all summer, which meant manager Mikel Arteta was delighted to bring him in.
The Ghana international enjoyed success while at Atletico, winning the Europa League, and he is hungry for more trophies at Arsenal.
And asked whether he is confident he will win trophies with the Gunners, Partey replied: “Yes, of course.
“It’s something that is difficult and we all know that it’s difficult, but we’re working towards it and I think we are ready. We have to go all out and try to achieve all of that ourselves.
“I’ve seen that everyone has been excited and everyone is willing to win something and all the trophies that come their way. I think that’s the goal and objective for everyone here and that’s my goal also.
“This is our new objective. That’s the objective of the club, of me myself, and I think that we have to get back to where we belong.”
