The goalkeeper told the Liverpool Echo: "To score 30 league goals in a season is amazing. Everybody knows what Luis can do and the goals he contributes to the team are very important for us.
"He doesn't surprise me anymore. I see him every day in training. It's not an accident, it's not luck, the reason he has scored so many goals is down to his ability. He is so good and we're very pleased to have him.
"We are an attacking team and to have scored 96 goals in the league already is a brilliant amount. Hopefully we can keep that going over the final three matches and finish the season strongly."
Liverpool currently sit five points clear of Chelsea at the top of the league table.
