Wales international Ramsey reckons a number of new players will arrive at the Emirates Stadium but he also predicts some familiar faces will leave.
Changes need to be made after Arsenal ended their sixth season without a trophy, despite challenging on four fronts. The Gunners' Carling Cup final defeat to Birmingham preceded a collapse that saw Wenger's side exit the Champions League, the FA Cup and the Premier League title race.
Wenger will now splash the cash to bring in some new recruits in the summer and it is a move that Ramsey, 20, welcomes.
"I expect Arsene will be active in the transfer market," he told The People. "There have been a few names mentioned and I am sure there will be a few players in and out.
"Obviously we haven't won anything for a long time. The pressure has grown and the fans have been quite vocal lately. But the spirit in the dressing room is the same as always.
"Everyone gets on with each other so there is nothing wrong there and, hopefully, we can win a trophy next season."
Reported Arsenal targets include Blackburn defender Chris Samba and team-mate Phil Jones, West Ham's Scott Parker and Shalke keeper Manuel Neuer. Arsenal duo Nicklas Bendtner and Andrei Arshavin could be amongst the players on their way out.
