Claudio Ranieri has warned Marseille that Inter Milan are "rejuvenated" ahead of their Champions League meeting on Tuesday.
Inter ended a run of seven Serie A matches without a victory as they overcame Chievo 2-0 on Friday to lift morale within the camp.
And Ranieri is hopeful they can build on that result when Inter host Marseille looking to overturn a 1-0 deficit having slumped to defeat in the first leg of their last-16 tie in France.
Ranieri said: "We will try to score but we must be careful not to concede. OM are a good team, strong and dangerous on the counter-attack.
"We know their qualities and their weaknesses. They have earned more points away than at home in Champions League matches but compared to the first leg, the mood and atmosphere in our squad is very different.
"Friday's success against Chievo has encouraged and rejuvenated us. We want to keep our Champions League campaign going and we are determined to get through. The team will not lie down and as [Dejan] Stankovic said, we have found confidence after a difficult period.
"The squad have always given everything and we showed that in Verona where we scored at the end of the game because we kept on fighting. Inter player never give up."
