The Brazilian is set to make his home debut against Toulouse on Sunday after shining in his first appearance at Guingamp, scoring the third in a 3-0 win.
Dupraz guided the relegation candidates to 13th in his first full season in charge last term after they narrowly avoided the drop in the previous two years.
The campaign included a four-point haul against then-champions PSG, with a 2-0 home win backed up by an impressive 0-0 draw at the Parc des Princes in February.
"We defended superbly [in that draw]," Dupraz told Le Parisien.
"We were not glamorous, of course. But people often forget that we have a €32 million budget.
"Neymar, all-inclusive, represents 15 years of operation of Toulouse."
The former Evian coach praised the wider impact of Neymar's arrival in France but remains eager to make up for "missing a chance" against Monaco.
"The signature of Neymar is a benefit for French football. I am neither envious nor jealous," he said.
"[Sunday's match] is a chance to play PSG, to play in Ligue 1, especially when we are the youngest team in France.
"It's a chance for me to sit on the bench for Toulouse at the Parc des Princes. It is an honour.
"The goal is to win."
