Spain Under-20 boss Julen Lopetegui has insisted that his side have to 'improve' despite winning their first World Cup game against USA.
Jese and Gerard Deulofeu both scored two goals each to give La Rojita a 4-1 win in Group A.
But the Coach has claimed that his team need to do better if they are to go all the way.
“We have a lot of things to improve on,” he told a Press conference. “Both with the ball and without it.
“We are moderately satisfied, but we have to work on a few things for the next games.
“I think the result was slightly excessive.”
