Hi Chile and Croatia will play a friendly match in Brazil before the WC, on June 5th. This gonna be the 1rst friendly match between both NTs in adult level (we played against Croatia in U20 WC this year). We don't know in which city the match will be played yet, but our NT will prepare the WC at Belo Horizonte (Minas Gerais, Brazil).
This friendly has not been confirmed by the Croatian football association but president of the association did say that a deal with Chile is close.
According to this Chilean website http://www.cooperativa.cl/noticias/...a-al-mundial-de-brasil/2014-01-08/072505.html, Croatia wants to play this friendly at Salvador de Bahía(north-east Brazil), and Chile wants to play it at Porto Alegre(south Brazil).
