'But I've always proved them wrong. And I did it again.
Hopefully now they can shut up.'
Marsch had originally reshuffled his attack after two insipid displays in warm-up games against Uzbekistan and Ireland.
Larin and Jonathan David, Canada's record scorer, hadn't clicked, and the lack of finishing was causing the coach to get cranky.
'We're going to score more goals,' insisted Marsch. 'So I don't have to put up with any more stupid questions from you guys.'
Marsch was just 12 minutes away from a full press conference worth of questions he'd find stupid. Larin helped him avoid feeling foolish.

David's glaring early miss and otherwise ineffective performance was probably the biggest negative from an afternoon that ended with such positivity.
Tani Oluwaseyi, who replaced Larin in the starting XI, blazed an equally great opportunity over. On the hour, Marsch called David ashore and replaced him with Promise David.
That lasted only 16 minutes until Larin was unleashed and did the business, thanks in large part to a delicious flick from Promise David in the buildup.
Marsch was asked if he hoped this would be the dam-buster for his entire attack.
'On one level you can say the subs we made [had] a big impact so they were some good decisions,' he said.
'But I gotta figure a way to get more out of the starters too.'
