Answer 1

Utiliser flatten(1) http://apidock.com/ruby/Array/flatten

your_array = [[["Club three Team one", 7800], ["Club three Team two", 7801]], [], [["Club four Team one", 7807], ["Club four Team two", 7808]], []]
your_array.flatten(1)
#=> [["Club three Team one", 7800], ["Club three Team two", 7801], ["Club four Team one", 7807], ["Club four Team two", 7808]]
