Also read that CR didn't protest per the requirements before the start of the match and didnt file a protest during the match with the Ref. This goes along with reports saying that CR wanted to play the game.
"Costa Rica could retaliate by staging the return fixture in the Saprissa stadium, an small but intimating venue where the fans are close to the pitch, rather than the new National Stadium, which has a running track around the field."
So, CR thinks it best to put the players in close proximity to the fans and allow them to be possibly hit by thrown objects. Sounds like they totally care about player safety...
i heard that the fans were throwing snowballs to Navas (goalkepper) during the game, so what diff does that make?, anyways i think usa team has always played in tibas
