And to expand on the statement "in the opinion of the referee". Just because he has an opinion it does not make him automatically right. But at the same time you cannot take the ability to make a decision whether right or wrong. A review of a contested goal seems to be in order. And in this particular case it would be to review if a hand ball had occurred the fact that the review would show an offside would be irrelevant.
And to keep the review to a minimum, if the play stands as call the captain of the team that made the request receives a yellow card.
