RB Leipzig star Tyler Adams believes the United States Men's National Team must step up their level in their coming games.

The United States were due to play friendlies against Wales and Netherlands before their coming World Cup qualifiers in September.

But those games will likely be their first when the squad gets together.

And Adams knows the players must be on their game from the off if they are to get the results they need to qualify for the 2022 tournament.

For his part, Adams has not played with USMNT since 2019 due to injury problems.

"I really have to prepare myself that the next time I put on the U.S. jersey, it's all or nothing, there's no more preparation matches," Adams told ESPN.

"It's either you go out there and win or we're not going to another World Cup."
