The participation for the third Formula One Indoor Trophy shrank to a record low of 5, representing five different teams.
The team, which used Dallara chassis, chose not to use its 1990 drivers Emanuele Pirro and Andrea de Cesaris.
Minardi, whose driver Luis Pérez-Sala had won both the previous Indoor Trophies, sent Gianni Morbidelli.
Finally, EuroBrun were represented by Domenico Schiattarella, who would not make his full F1 debut for another three and a half years, instead of their regular drivers Roberto Moreno and Claudio Langes.
Chaves was given a bye to the semi-finals, while the two Italians, Morbidelli and Schiattarella drawn against each other, and the same with the two remaining foreigners, Lehto and Grouillard.
