And the first chance to prove that is at home to runaway Premier League leaders Manchester City on Sunday.
It would also give Klopp the option of deploying him behind Roberto Firmino in a 4-2-3-1 system, directly filling the gaping hole Coutinho has left and catering for the development of a suitable ecosystem for fellow attackers Sadio Mane and Mohammed Salah to thrive, occupying the wide roles.
"It's normal in the business".
"It is normal to lose players and buy players and you must always react". It is all about the atmosphere in the club.

After putting pen to paper on a five-and-a-half-year deal at the Nou Camp, which will see him earn around £12m-a-year, Coutinho said: 'I'm very, very happy.
