The strikers have scored 40 goals between them this season, and the Belgium international believes that playing against the pair in practice games has improved his shot-stopping abilities.
He told the Liverpool Echo: "It's nice to work with Luis and Daniel day in day out as it makes you better as a keeper.
"We all know what they can do and it's unbelievable. I see that quality every day.
"When you are one-v-one with strikers of that quality, you learn a lot of things."
Mignolet became the most expensive keeper in the Reds' history when he was signed from Sunderland for around £9m last summer.
