Christian Pulisic believes the United States can take confidence from setting a record for away goals as they thumped Grenada.

In winning 7-1 on Friday in the CONCACAF Nations League, it was the first time they had scored seven goals in a match taking place outside the US.

It was USA's first competitive match since the World Cup, with Ricardo Pepi and Weston McKennie each scoring twice.

Chelsea star Pulisic also got on the scoresheet, and had a hand in four other goals too.

"We came out really strong with a lot of energy and just kind of put with them right away," Pulisic said.

"So I think they were kind of surprised by that. Took our goals well and just a great all-around performance. Definitely gives us confidence."

The game was also the first time USA played a competitive match without using a single MLS player since the league began in 1996. 

Interim coach Anthony Hudson was impressed by what he saw from his team, but urged them to finish the job as they bid to reach the Nations League final four.

USA are top of their group ahead of hosting El Salvador on Monday at Exploria Stadium in Florida.

Hudson said: "With a [good] performance and a result like this, you don't want to get carried away.

"The importance for us is just to make sure that we do all the right things between now and the next game and we finish the job off. 

"But the actual performance, I thought it was the result of just a really, really good week."
