Liverpool goalkeeper coach John Achterberg hopes Alisson's goal last season is a one-off.
The Brazil goalkeeper's wonder header earned the Reds victory at West Brom and sparked their successful push for a top four finish.
"I hope [another goal from him] is not needed because then the score is not right for us," Achterberg told Liverpoolfc.com. "Hopefully we're always on the right side of the score!
"We never know. He's not the first goalie to score but for Liverpool he was and that was a really important one.
"Hopefully he can just have to focus on the goalie side and try to win games by keeping the team in the game.
"It was an unbelievable, magic moment. After everything he'd been through this year off the field as well, it was a nice way but also at that time an important thing for us as a team and as a club because we were chasing the Champions League.
"It was great that he finished it with an unbelievable header. It was a great moment for him and I'm happy for him for that.
"You know he can play football – obviously I didn't see him head the ball in like that! But when he is in the small-sided games, he can hit the target as well and has got a decent strike on him and he can play football as you can see on the field.
"He is quite good with the ball. To head a ball like that, it was unbelievable."
