The Brazil international completed a much-anticipated move to Barcelona in the January transfer window in a deal worth a reported £146m.
Liverpool FC managed to keep Coutinho at the Anfield outfit for the start of the 2017-18 season despite the South American’s desire to move to Camp Nou.
Coutinho contributed 12 goals and eight assists in 19 appearances before his January switch to Barcelona.
However, Liverpool FC’s goals haven’t dried up since Coutinho’s exit as trio Roberto Firmino, Sadio Mane and Mohamed Salah continue to flourish.
The Reds trio have scored 50 of their 73 goals in the Premier League this season to highlight their impact on the Anfield side.
Former Chelsea FC striker Sutton believes Coutinho’s exit has become a distant memory following the impressive performances of Firmino, Mane and Salah.
“The most incredible thing about Liverpool FC is Coutinho has gone and there was such a big fuss about it,” Sutton told BBC Radio 5 Live.
“Nobody notices now. When was the last time anyone mentioned Coutinho? For the money he went for and the impact he had at Liverpool. It shows the job the front three have done.”
Egypt international Salah has scored 28 times in 30 games in the Premier League this term following his £39m move to Liverpool FC from Serie A giants AS Roma last summer.
The Reds are set to take on Premier League leaders Manchester City in the Champions League quarter-final next month.
