As outlined by Sky Sports, he told reporters at his pre-match press conference ahead of tomorrow night's trip to Hull City that the club needs to get the forward back to full fitness on a consistent basis after a nightmare season when it comes to injuries - with a hip problem currently keeping him out of the side.
Rodgers said: "It's been difficult, Daniel is a good lad who wants to play and work and help the team but it's been one of those seasons for him.
"He's been very unfortunate and we'll have to monitor day-by-day and see where he's at. When he's been fit, he's been brilliant, it's just getting him back on a consistent basis. Whether that's this season, or pre-season, has to be seen."
The Reds boss has said the forward area needs addressing in the summer with the lack of firepower proving to be a big factor in not backing up last season's title challenge - when both Sturridge and the now departed Luis Suarez were the top two in the Premier League goalscoring charts.
One thing that has improved during the second part of the season is the defending - the Reds have kept a total of 14 clean sheets across the campaign, with Simon Mignolet now in contention for the golden glove.
"If you look at the numbers, at the same point last year, we had 90 goals. You're nearly talking about a 100% difference.
"Defensively we've been strong, despite what people write and we had a 14th clean sheet. Top five defensively in the league. But obviously the critical area, as it was when I first came, was goalscoring - and it's something we need to improve."
The weekend's draw against West Bromwich Albion, combined with other results means Liverpool are seven points off fourth place with a game in hand. A win tomorrow night can close the gap to four points with five games remaining, so there is still a slim chance the Reds can sneak into the top four.
Rodgers has said the side has set new goals between now and the end of the season, saying: "We've set new goals for the remainder of the season and it's focusing on the performance level in order for us to win.
"The teams above us, they have the clear advantage, but you can only affect that by winning games, starting with tomorrow evening. We can only focus on ourselves but there's lots of changes that can take place and we have to give everything to finish as high as we can."
