The Ligue 1 champions drew 1-1 with Chelsea in the first leg of their last 16 UEFA Champions League tie in Paris on Tuesday, a result that extended their unbeaten home run in European competition to 33 matches.
PSG will feel aggrieved they could not win on the night, though, and now face the unenviable task of going to London and trying to get a result.
The result was at least an improvement on a poor 2-2 home draw with Caen last time out for Laurent Blanc's side.
Blanc's side remain third in the table, two points adrift of leaders Lyon, and Silva is desperate to avoid a repeat of the Caen collapse.
"The Champions League brings a certain extra motivation," he told the club's official website.
"We need to do the same in the league [though], starting this Saturday.
"The match against Toulouse is also very important."
Alain Casanova's side sit 17th, just two points above the bottom three.
More encouraging for PSG is Toulouse's terrible away record in recent times.
Only two teams have conceded more than Toulouse's 37 Ligue 1 goals this term, also.
