Neymar has blamed the pitch after his embarrassing penalty miss in the 1-1 friendly draw between Brazil and Colombia in New Jersey.
Neymar - who earlier had scored Brazil's equaliser, fooling his marker with a drag-back before shooting between two defenders - fired his 80th-minute attempt wildly over the crossbar after an elaborate run-up.
"It was horrible," he said afterwards. "The pitch was completely unstable. It wasn't just the penalty - the pitch didn't help the game as a whole."
Kaka also offered extenuating circumstances for the spot-kick howler, saying: "The field was difficult - you saw that during the penalty kick. It wasn't a perfect field, but I don't want to complain about it."
Colombia goalkeeper David Ospina agreed with Kaka's conclusion, adding: "The ball bounced differently and the grass itself separated from the surface easily.
"He kicked the penalty really high. I think the grass played a role in it, but it was like that for both teams."
