Nacho Scocco hopes his move to Sunderland can earn him a place in Argentina's World Cup squad.
The striker made his debut in their FA Cup win over Southampton.
"I will work hard to get back to how I played in Argentina and reach the same level from Newell's," Scocco told the Evening Chronicle. "It's difficult to play in the national team, because there are many top-level players.
"But I will try to work every week and every game to try to get there.
"The World Cup is always on the mind of every player, but I know it will be difficult.
"I think playing in the Premier League will help though."
