Nehru Cup 1991
According to FIFA (see RSSSF) only Hungary and India were "A" Teams.
Confirmed in "magyarfutball.hu", where only "Hungary vs India" is listed
as official Match.
If the above is true, also Zambia and China (in addition to Soviet Union) have to be labelled as XI Sel.
But: is it true or not?
Soviet Union took a strong but young team. Apparently, 11 of the 18 players on their team were part of the European Championship final-reaching team (presumably the 1990 European U-21 Championship and not the 1988 European Championship). Zambia took a team of 16-18 year olds, so definitely not the national team. China was actually Liaoning.
