The Brazil international was Liverpool’s star player on the opening weekend of the Premier League season after Coutinho cancelled out Theo Walcott’s opener at the Emirates Stadium with a brilliant free-kick which beat Arsenal goalkeeper Petr Cech.
The South American netted his second goal of the game sandwiched between strikes from Adam Lallana and Sadio Mane in Liverpool’s 4-3 victory over the Gunners, and the former Inter Milan star man was only denied his hat-trick by a fine Cech save in the second half.
Coutinho, who moved to the Reds in an £8.5m deal from Inter under Klopp’s predecessor Brendan Rodgers in January 2013, scored just five times in the Premier League last season in an injury-hit campaign.
Former Liverpool defender Carragher explained why he has been surprised by Coutinho’s performances under Klopp.
“In the past two years he has become Liverpool’s best player and he has surprised even me with the way he has responded to working with Jurgen Klopp; I thought he would find the extra intensity difficult at first, especially playing in a wide role where you are required to cover more ground,” Carragher told The Daily Mail.
Liverpool are bidding to win their first top-flight crown since 1990 after an eighth-place finish under Klopp last term.
