Likewise (there are eleven players in both cases so you need a word that means "the same")
But ("oval" and "round" are not the same shape so you need a contrasting word)
On the contrary (hands and feet are not the same method so you need another contrasting phrase)
Both (either way indicates that despite the contrasts, there is a similarity between the sports so you need a word referring to soccer and football)
