BERLIN — Borussia Dortmund squandered a three-goal lead and drew with Hoffenheim 3-3 at home then watched Bayern Munich cut its lead in the Bundesliga to five points on Saturday.
"Anyone who doesn't believe in the title should stay out of the dressing room," Napoli defender Kalidou Koulibaly said. "As long as it is mathematically possible, I will continue to believe right until the end.
"We are very competitive, we want to win and keep getting closer to Juve. We have to keep on fighting."
The 79th-minute goal was Inter's first in Serie A this year.
"I'm very happy because we got back to winning ways and that was the most important thing," Lautaro said.
"Our mindset is very important, things haven't been going as we wanted them to for a few matches. "We want to keep our distance from the chasing pack and achieve our aim, which is qualifying for next season's Champions League."
Gervinho had earlier hit the crossbar for Parma, while Inter defender Danilo D'Ambrosio had a goal ruled out after video review showed the ball came off his arm.
PARIS — Facing a rampant Manchester United side in the Champions League was already a tough enough prospect for Paris Saint-Germain.
