However Curbishley is not moved by the criticism and is confident of more new arrivals before the Premier League gets underway a fortnight on Saturday.
He told the club's website: "Contrary to some reports we are fully committed to strengthening the playing staff.
"There will not be a mass exodus and fans can be assured we are working as hard as always to ensure high-calibre competition in all areas of the team.
"Since the new group took over West Ham we have tried to push forward and I don't see selling players as a way of pushing forward.
"I want to see certain combinations of players that I haven't had a chance to see. I want to play Craig Bellamy with Dean Ashton.
"I know when I do get them all in that we are a quick offensive side and if we get everyone fit we are in a position to push on. We have a squad that is strong enough to challenge for the top six."
