I think that despite the fact that Coutinho moved to Barcelona, Liverpool will be able to achieve great results. I really like how now the team plays under the guidance of Klopp.
That's a maybe. Klopp's teams are known to fade at the second half of the season due to fatigue.
What they should do with all that Coutinho money is acquire a player or two before the transfer window closes... With them still being in the CL they'll need the back up in the EPL and in whatever cup games they're still in.
