In terms of postgame handshake rows, this has to be far and away one of the best ones yet.
At the full-time whistle, Pareja greeted Timbers boss Caleb Porter with a tissue he had just blown his nose with as opposed to his hand.
Porter was not amused. He dismissed the tissue and gave Pareja a not-so-subtle "scoreboard" mention.
"I walked over to shake his hand and he had a tissue that he put over his nose and tried to hand me a tissue," Porter said afterward, per MLS. "So I thought it was very poor sportsmanship out of (Pareja).
"I never said one word to him the whole game and he obviously wasn't happy with the loss."
In the aftermath, former United States star and Fox Sports analyst Alexi Lalas weighed in on the issue and sided with the Timbers boss.
