Arsene Wenger's men led the way for much of the campaign in a thrilling title race last season, but fell away in the second half of campaign to eventually finish fourth.
Ramsey's absence with a thigh injury coincided with Arsenal's drop off in form as Manchester City eventually edged out Liverpool to claim a second Premier League crown in three seasons.
The Wales international returned to score an extra-time winner as Arsenal beat Hull City 3-2 to win the FA Cup, and will hope to guide the London club to victory against the English top-flight champions at Wembley in the Community Shield on Sunday.
"I think there's going to be a few teams in it this year. I think maybe about six teams," Ramsey said.
"Teams will take points off each other, anything can happen but there's five or six teams that are going to be really strong this year."
And Ramsey is relishing the challenge of taking on Manuel Pellegrini's men.
"We're all looking forward to it, me personally as well," he said.
"After what went on last year, looking forward to going back there [Wembley] and playing there again. We're all excited and looking forward to it being a successful day for us.
"They [City] are always very strong, and it will be no different on the weekend again. They have so many world-class players playing for them. It's going to be difficult but we'll be up for it and hopefully we can get the right result."
