Wernbloom double seals Sweden success
Sweden went ahead six minutes after the break when Wernbloom headed home from close range after a great cross from the right by second-half sub Sebastian Larsson.
The Swedes were allowed more space as Hungary pressed in search of an equaliser and Wernbloom added his second from close range after a Kim Kallstrom corner in the 73rd minute.
Zlatan Ibrahimovic, who quit international soccer last year after Sweden's failure to qualify for the World Cup before making a U-turn last month, had the best chances before half-time but Ola Toivonen and Johan Elmander also should have scored.
Overall, though, the victory was well earned in new coach Erik Hamren's first competitive game in charge for Sweden.
