The Reds secured a return to the Champions League last season thanks to fourth-place finish ahead of Arsenal in their first full campaign under Jurgen Klopp.
Liverpool secured their place in the group stage thanks to a 6-3 aggregate win against Bundesliga outfit Hoffenheim last month.
But the Reds made a disappointing start to the Champions League proper after conceding in the fifth minute at Anfield on Wednesday night.
Liverpool responded thanks to goals from Roberto Firmino and Mohamed Salah before the Brazil international missed the chance to make it 3-1 from the penalty spot.
Sevilla were second best for most of the European clash but levelled with 18 minutes to go thanks to Argentine midfielder Joaquin Correa.
Former Manchester United midfielder felt that Firmino’s penalty miss proved the decisive moment in the Champions League clash.
“The penalty was defining factor of the game,” Ferdinand told BT Sport. “If Firmino scored it, it was game over, 3-1.”
Liverpool have won two of their opening three Premier League games in the 2017-18 season so far.
The Reds lost 5-0 to title rivals Manchester City last time out.
The Merseyside outfit will return to Premier League action with a home clash against Burnley on Saturday.
