End argument? Vis-a-vis league title, it might (4,10)
I believe the answer is:
goal difference
'title it might' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'end argument? vis-a-vis league' is the wordplay.
I cannot really understand how this works, but
'end' could be 'go' (going is a kind of ending) and 'go' is found within the answer.
'argument?' could be 'difference' (argument is a kind of difference) and 'difference' is present in the answer.
'a' is present in the answer.
'league' could be 'l' (abbreviation) and 'l' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for goal difference that I've seen before include "Tie-break system" , "tiebreaker?" , "separates those for from those against" .)
