Bigger than, Biggest ever, etc.
This is not about who is bigger than. This is about the municipality. Not about the metro area. That is another topic. Not about the province. That is another article. Not about Greece. That is another article. Not about the EU. That is another article. We would like to concern ourselves to Thessaloniki city only. If you would prefer to maintain the higher level articles on the metro area, I am sure the editors would welcome you there. We are not trying to "compete" with them nor duplicate what justly belongs in their article and justly does not belong here.
