The Italian has only just returned from a three-month absence with a broken foot which could not have come at a worse time for him.
By the time he had recovered manager Brendan Rodgers had signed Sturridge for £12million and the striker has responded with three goals in as many games.
Seeing Sturridge ahead of him is a familiar sight for Borini as the 23-year-old edged in front of him in terms of first-team recognition when the pair were at Chelsea together.
"Competition in positions is good because everyone is fighting for their place," Borini told Press Association Sport.
"Daniel and I were together in the reserves, going backwards and forward from the first team, as we were the same position.
"Then I had a problem with my contract and I was back with the reserves.
"There was some rivalry for the position, like every team has, but we are good friends too. You have to fight for your place all the time, even in life.
"It is a big chance for us (him and Sturridge) because we always waited for this chance to be part of a big project at a big club.
"We both know Brendan and the way he thinks and works so that is helping us but we have to do our job as well."
