The Brighton & Hove Albion midfielder enjoyed his full debut for the Under-21s in their Toulon Tournament opener against Qatar on Thursday and capped his performance with a goal in the 3-0 win.
Gareth Southgate’s squad will next be in action on Monday when they take on the South American giants, who beat Korea Republic by 2-0 in Group B immediately prior to England’s match at the Stade Leo Lagrange.
And Forster-Caskey is hoping his display against Qatar will be enough to ensure he is involved in some shape in St-Raphael next week.
"It’s a game that everybody wants to play in," admitted Caskey, who is back in an England squad for the first time since 2011 when he was capped at Under-18 level.
"It will be a good test and hopefully we can win again.
"I was just happy to start at first and wanted to do well for myself and the team.
"I’m happy to get on the scoresheet and it’s a good start to the tournament."
The 20-year-old certainly impressed in his advanced midfield role against Qatar and could have come away with more than one goal in the end.
It is a role in the team which he clearly enjoyed and his display will certainly have given Southgate food for thought with three more group games to go in Toulon over the next week.

"I have played in a deeper role as well, but I do enjoy it being closer to the strikers because it means I can shoot and try to get some goals as well.
"But it’s been easy for me to come in and just train hard, as I knew a few of the boys before and I just want to do my best really.
"There’s Solly March here from Brighton as well, so we’ve come together and it’s been easy really, the other lads have been quality."
