Economic data over recent weeks have supported that conclusion, suggesting the eurozone recovery has continued throughout the region in the latter part of the year but that growth isn't electric.
The economy of the 17 EU countries that use the euro grew by a quarterly rate of 0.3 percent in the second quarter, which brought an end to the single currency zone's longest-ever recession.
Figures next month are expected to show that the eurozone grew at a similar rate during the third quarter of the year.
James Ashley, senior economist at RBC Capital Markets, said the main message from Thursday's survey was that growth continues at a modest pace.
"For now, let's not quibble over whether that is shaping up to be a 0.2 percent pace or a 0.3 percent pace," he said.
