This is a fight between two past their best featherweights who are similar in many ways. Both aren’t big punchers and both are 35.
I really don’t see much of a difference between the two though McDonnell is bigger and has fought at a higher level in the past.

I think after twelve rounds Gavin McDonnell will have done enough to win a decision due to his height advantage and him having fought at a higher level than a Gago.
