Arsene Wenger’s side warmed up for the new Premier League campaign, which kicks off next weekend, with a ruthless dismantling of the champions at Wembley on Sunday.
Wales midfielder Ramsey scored Arsenal’s second goal after Santi Cazorla’s opener and Olivier Giroud’s superb long-range strike sealed a morale-boosting win.
It was the perfect way to maintain the feelgood factor from last season’s FA Cup final triumph over Hull City, a victory which ended the Gunners’ nine-year trophy drought.
After going 3,283 days without silverware, Arsenal have now won two trophies in four months and Ramsey is convinced his team are destined for more success in the coming season.
“The atmosphere in the camp is great. We really want to work hard for each other and the club is on the up,” Ramsey told BT Sport.
“Everyone is excited and the arrival of Alexis Sanchez has made everyone excited.
“After the FA Cup win I really feel this club is on the up and I hope we can go on to be very successful in the coming years.”
Ramsey’s strike followed hot on the heels of his extra-time winner in the FA Cup final, while Cazorla also netted again after scoring against Hull.
“It has not been a bad place for me or Santi Cazorla. We want to play here every week!” Ramsey said.
“I have just become a lot more composed in front of goal, realising I have more time than I did in the past.
“We have prepared well and it paid off as we came out 3-0 winners. They couldn’t get near us for the first 25 minutes.”
Giroud’s brilliant 30-yard effort was the pick of the goals, but the France striker claimed he was slightly fortunate to have scored from such a distance.
“I felt I could shoot, I was a bit lucky but I did what I really wanted to do and scored,” he said.
“I think we will be stronger this year. We are getting better and better and I think we will do very well.”
