Hakan Calhanoglu feels victory over Champions League opponents Barcelona can spark Inter Milan's season.
Inter allowed Barca to have possession at San Siro and strike on the counter, which is what happened when Calhanoglu struck the winner for the hosts.
“It was very important that we get the win tonight, we had to send a signal above all to the fans, who are always close to us," Calhanoglu told Sport Mediaset.
“They gave us a big hand this evening, we proved that we deserved the victory. This game can really shake us up and change our season, because we want to build on it.
“As for qualification, we've got to stay calm and take it one game at a time."
