Liverpool manager Jurgen Klopp has no doubts his attacking 'Fab Four' will gel together but accepts they just need time.
The Reds boss started with his key quartet of Philippe Coutinho, Sadio Mane, Roberto Firmino and Mohamed Salah for the first time in a competitive game in the 1-1 Champions League draw at Spartak Moscow.
Coutinho, after a smart one-two with Mane, equalised Fernando's free-kick but - despite creating a number of chances - they could not force a winner even after the introduction of striker Daniel Sturridge.
'It is good when you have all these players but it is not (just) lining up the players, they all need rhythm and it was a very intense game,' said Klopp.
