He told the Liverpool Echo: "The relationship [between the front players] off the pitch is really strong, and on the pitch, the link-up play and everything is always good.
"But these players are also paid to be selfish and we need them to score goals and take risks in the final third, and we add [Diogo] Jota into that category now.
"When they are in front of goal, we expect them to shoot and score.
"There have been certain occasions where people say Bobby could have passed, Sadio could have passed, or Mo could have passed, but these guys are paid money to make split-second decisions and score goals for us."
He added: "Their relationship is really strong just like every other relationship in the squad and that is why over the last couple of years we have been quite successful.
"You get nowhere without these relationships."
