Speaking to club media during pre-season (20 July), Keita outlined his ambition to get more goals next season.
Jurgen Klopp’s side will be challenged with replacing the 23 goals scored by Sadio Mane this season.
The Reds have signed Uruguay striker Darwin Nunez from Benfica this summer.
When asked by Football Insider if Liverpool’s midfield should step up and score more, Robinson said: “Over the past few years, regardless of who plays, the front three at Liverpool scored all of the goals.
“It was difficult for goals to come from elsewhere because the actual goal threat is pretty much exclusively the front three. When you have the quality Liverpool have got, the majority of the goals are going to come from three of the five forward.
“If they are going to get goals from midfield their style will need to change. I think that will happen this year though.
“Nunez plays more as a nine. He is certainly more of a nine than they’ve had previously. He will not play off the flanks. Therefore, their style of play will change.
“It might open up more space for the likes of Keita to contributed more goals from midfield.”
