We'll also get Germany's ZEW survey of economic sentiment at the same time, which should give us a good idea of how businesses and consumers are taking the recent grim news about the country's slowdown.
We've already had some worrying data out this morning: French inflation dropped to 0.4% in September, a five year low, and Spain's figure came in at -0.3%, the third straight month of deflation.
