BBC Sport - World Cup 2014: Messi targets Argentina improvements after win

Room for improvement - Messi

Argentina striker Lionel Messi insists his side need to improve, despite beating Bosnia-Hercegovina 2-1 in their opening game of the World Cup in Group F.

Messi lit up the second half in Rio on Sunday night with a dazzling piece of skill, jinking past two defenders and providing a neat finish to beat Bosnia keeper Asmir Begovic for Argentina's second goal.

Argentina's next game is against Iran in Belo Horizonte on Saturday.
