Gustavo Henrique’s men had suffered the indignity of an 11-1 opening loss to Brazil at Dubai International Marine Club, and Patrick Tepa’s hat-trick helped inflict another reversal on Wednesday. In response, Kamal Ali Sulaiman, Ali Karim and Mohamed Al Zaabi all scored.

The Whites – who finished third in 2012 and 2013 – will now search for their first win of the sixth edition against Poland on Thursday, while Tahiti’s triumph keeps alive their hopes of topping Group A with a victory against Brazil.

Elsewhere in the same pool, 13-time world champions Brazil were pushed all the way by Poland in an eventual 5-2 victory.

The recent FIFA Beach Soccer World Cup qualifiers from Europe were leading 2-1 late into the second period, only for a double from Rodrigo to help the favourites maintain an 100-per-cent record.

Holders Russia showed their class with a dominant 9-3 triumph against the sorry United States, while the other Group B-contest ended in a 4-1 victory for Iran against Egypt.
