Costa Rica take on Serbia in a vital Group E fixtures.
Costa Rica will be looking to build on their 2014 showing. Their World Cup warm up has been far from ideal as they lost all their friendlies.
Serbia have won all their previous fixtures against CONCACAF opponents, a fact that Krstajic will no doubt touch upon in his pre-match talk.
I am tipping Serbia to win this one. Back Serbia on Bet365 for the best odds.
