Not particularly knowledgeable about such things, so I may be wrong on any of the points below.
It has fittings for mudguards (on the rear at least) and the Champion Mondial AA was a top of the range racing bike. I would also expect to see a fitting under the top tube for a racing number.
I haven't seen lug cutouts in that shape on a Gazelle before and there is no Gazelle pantographed into the fork crown.
The rear brake cable and shifters have band-on mounts; the rear derailleur cable stop is on top of the chainstay: all point to a 1970s bike. Does the cable guide go over or under the bottom bracket? I've not seen a CM AA that old.
Having said that, it does look to be a decent frame (what diameter is the seatpost) and EUR80 seems like a good price; who knows you might have something even better!
In trying to ID the frame, I'd concentrate on the combination of lug cutouts and the detail on the top of the fork crown.
