Coutinho was best man at Firmino's wedding last summer.
The 26-year-old Brazilian is said to be one of the players Liverpool want to tie down, but they want to offer him a special deal.
Last week, the Liverpool fanbase was rocked by the news that a fee had been agreed upon for the sale of Philippe Coutinho to Barcelona.
Despite handing in a transfer request, however, Coutinho continued to perform at a level expected of him and his farewell message to Liverpool fans was, by and large, well-received.
How will Liverpool manager Juergen Klopp ensure that doesn't happen? Lallana is still not fully up to speed but when he is, the England worldwide is an important part of Liverpool's team pressing, mobility, and ball-carrying in midfield.
As per the provided Telegraph link, Liverpool are sure that the front three players will be settled at Anfield for the years to come. "I will work hard to live up to the expectations of me in training and on the pitch".
Klopp's side are unbeaten in 17 games in all competitions since they were thrashed 4-1 by Tottenham on October 22.
This time they will have Virgil van Dijk in their way with the Liverpool defender set to make his Premier League debut after his move from Southampton.
RB Leipzig intend to resist Liverpool's attempts to bring Naby Keita to the club in January, according to reports. He has been making far more unnecessary fouls, and has become more isolated from his team mates.
Guinea global, Keita, will be Liverpool's record transfer when he signs for the Anfield club officially in the summer.
Keita will remain in Leipzig colours this season, the German side insist.
