Coutinho began the new campaign in spectacular fashion when he fired home a long-range effort to give the Reds an opening-weekend win away to Stoke City and help banish the memories of the painful 6-1 reverse to the Potters on the final day of last term.
However, the Brazil international’s form has dipped in recent months and the playmaker struggled to make an impact on games in the final third as the Reds laboured in the dying embers of Brendan Rodgers’ reign.
Coutinho endured a quiet first 45 minutes against Chelsea at Stamford Bridge on Saturday before springing to life in stoppage time with a curled effort to equalise in their 3-1 win over the champions.
The former Inter Milan youngster then recorded his brace in the second half before Christian Benteke put the icing on a superb performance against Jose Mourinho’s side, and the win has truly ignited the reign of Jurgen Klopp who took over last month.
Former Manchester United defender Ferdinand was impressed with Coutinho’s display in west London, and the ex-England centre-back tipped the 23-year-old to become one of the Premier League’s leading lights.
Ferdinand told BT Sport: "This little fella is a genius and if he can get on the ball and twist and turn and make things happen then he can become a world-class talent if he does it on a regular basis.
"He needs to get more consistent and he'll have more of a chance of being a world-class talent."
Klopp’s side return to action when they travel to Rubin Kazan in the Europa League on Thursday before hosting Crystal Palace on November 8.
