West Ham winger Manuel Lanzini could be left out of the Argentina squad for Tuesday's clash with Spain after picking up a knock while on international duty.
The 25-year-old is not fully fit and skipped training with Lionel Messi and Co at Real Madrid's base on Sunday.
It will come as a worry for David Moyes and West Ham, who face Southampton in a relegation six-pointer at the London Stadium this Saturday.
Lanzini has only contributed three goals and five assists in the Premier League this season, though is continuing to attract attention from Liverpool.
