El Salvador and Bolivia will renew their rivalry after more than a decade when the sides meet at a neutral Audi Field in Washington DC on Saturday for an international friendly.
This will be their first clash of any kind since 2008.
Both sides have important World Cup qualifying fixtures coming later on in the month and are looking to use this occasion to try and experiment with their lineups.
La Selecta are languishing in seventh place in the third and final round of the CONCACAF qualifiers with just one win in six games, having scored only twice.
La Verde, meanwhile, are in the exact same position in the CONMEBOL zone, with only three wins from 12 clashes.
With 12 points in the bag, they trail fifth-placed Uruguay by six points and still mathematically have a chance of qualifying for their first World Cup since 1994.
El Salvador vs Bolivia Head-To-Head
The sides have met only four times in the past, with El Salvador and Bolivia both winning once each.
Following a pair of draws in the 90s, Bolivia drew first blood in 2006 with a thumping 5-1 victory.
El Salvador exacted revenge two years later with a 2-0 win.
