The Brazilian is eager for his side to put recent defeats behind them - and ease the pressure on coach Laurent Blanc - ahead of the clash with Lyon on Saturday
PSG go-to-head with Ligue 1 rivals Lyon in the showpiece event at Stade de France but defeat would only increase pressure on coach Laurent Blanc.
The three-time champions, who remain on track to defend their Ligue 1 crown, suffered back-to-back losses for the first time this season after falling to Chelsea in the Champions League and Lyon in the space of a week.
But Thiago Silva has urged his team-mates, who will be without star striker Zlatan Ibrahimovic, not to dwell on previous results, including their narrow league defeat at the hands of fifth-placed les Gones.
"The last defeat affected us as we could see last Sunday," said the Brazil international.
"However it is quite normal after two difficult games like these ones which we had to play.
"Now it is up to us to react. We need to react, especially as a team like ours, with so much quality.
"We have to get a result in order to take the trophy tomorrow, which is very important for all of us and the club."
