Arsenal finished third in the Premier League last season and also retained the FA Cup with a 4-0 win over Aston Villa at Wembley on May 30.
Arsene Wenger has since signed Petr Cech from Chelsea and remains in the market for further top-class additions, but Bellerin believes even the current team is capable of mounting a serious challenge for silverware.
“I’m really, really excited for the new season,” he told Arsenal’s official website. “The way we finished this season, the team have really come together and we’ve had some great performances, especially since the New Year.
“The team really feel like we can beat any team in the world with the performances we’ve had, so we’re all really, really excited to hopefully start the season with the right mindset and with the right results. Hopefully by the end of next season we can win some more trophies.
“We need to start with the confidence that we finished this season with. That’s going to important for us, to keep pushing and start where we left off at the end of last season.”
Bellerin enjoyed a breakthrough season at Emirates Stadium, making 25 starts in total, and the 20-year-old hopes to build on that success in the coming months.
“My goal has always been to improve, work hard and fight for a place in the starting XI,” he added.
“Last season I got the minutes that I was hoping for and I hope that next season I can do the same.”
