Manager Arsene Wenger insists Arsenal have no reason to sell their best players and can finally work to strengthen the group.
The Frenchman admits that the Gunners were forced to sell top players like Samir Nasri and Robin van Persie to overcome a financial restriction in the past but they are now in a very strong financial position.
They signed Mesut Ozil from Real Madrid for £42.4m two seasons ago and Chile's Alexis Sanchez from Barcelona last season for £35m.
They are expected to again be very active during this summer's transfer window with the likes of Karim Benzema, Gonzalo Higuain and Arturo Vidal all linked with a possible move to the Emirates.
"The time where we had to sell our best players is over for sure," Wenger said.
"We had five or six years where we were financially restricted, we had to balance the books and we had to pay the stadium back. This time has gone.
"It was a very sensitive period and mentally a very difficult period. But now we are over that.
"Now we are competing with everyone on a financial front and I think we can keep our best players."
