BANGKOK (AFP) - Brazilian wonderkid Neymar scored his first goal in Barcelona colours as the Catalan giants swatted aside Thailand 7-1 in a friendly in Bangkok on Wednesday.

Spain international Pedro notched a neat hat-trick, while Argentinian Lionel Messi scored a brace - including one from the penalty spot - in a first half appearance that delighted the near 50,000-capacity crowd at Bangkok's Rajamangala stadium.

Second-half substitute Alexis Sanchez scored the visitors' seventh and final goal early in the second half as new manager Gerardo Martino's side cruised to a routine win over a plucky but callow Thai side.

Thailand's star striker Teerasil Dangda scored the hosts' consolation goal from the penalty spot in the last minute of the first-half following a bungled tackle by young Cameroonian centre-half Frank Bagnack.
