Matheus Cunha lifts the lid on Brazil's World Cup hurt
It marked a difficult end for the Selecao at this summer's tournament as they entered a 12th year without successfully reclaiming their five-time world champions' crown.
Manchester United forward Matheus Cunha was one of the rare lights for his country with three goals in as many games before the surprise defeat at MetLife Stadium.
He netted twice against Haiti in their second group encounter before following it up with another to cap off a resounding 3-0 victory over Scotland in the finale.
But the 27-year-old could not hide his pain in the wake of their tournament exit.
"Without a doubt, today must be the most difficult day of my life, professionally speaking," he told Globo.
"We had chances we didn't convert, while they had chances and converted them. "It's difficult to try to understand everything but, unfortunately, that's part of football.
"There is a lot of sadness in the dressing room. A lot of crying. A lot of pain. The worst thing is that we frustrated a lot of people and that is what hurts most."
