That's right we were in a Euro qualifying campaign mess in 1987. We only qualified by a point. :D
Brazil were not the same draw in 1987 that they would be now. We actually totally sold out Belgum a few weeks earlier.
I would expect Brazil to sellout even combined with another game. The block bookers will have to buy or lose their BB. Brazil are probably not the draw they were almost 4 years ago but still an attractive tie.
It may depend also on the World Cup draw. An attractive group may rekindle interest. A new manager would also help.
