The Reds were in rut in November and December, and it looked increasingly unlikely they would repeat any form of last season's heroics where they finished in second place and qualified for the Champions League for the first time in five years.
But Sturridge has said 'hard work and perseverance' has been part of it, as Liverpool's switch to a 3-4-2-1 system has played a big part in the side's turnaround in form which has seen them go unbeaten in the Premier League in 2015 so far.
He said: "We're in a good moment, so we're just continuing to work hard each day out on the training field, putting in the work and hours.
"Then at the weekends, we're going into the games with a confident mentality and a positive attitude.
"The boys have fought back and we're where we are now, and that is testament to the hard work everyone has put in to get to where we are today.
"It [the formation] is working. Everyone is defending very well, Si [Mignolet] is doing extremely well also. It's great to see and long may it continue."
Liverpool are on a five-game winning run in the league which has seen them win key fixtures against Tottenham, Southampton, Manchester City, Burnley and Swansea. On Sunday they face Manchester United at Anfield knowing that a win could overtake their fierce rivals, and strike a blow in the race for the top four.
You would have got a big price on the Reds finishing in the top four a few months ago but the Reds are now even money to complete a remarkable turnaround this season, and Sturridge - who has recently returned from injury after missing most of the first half of the season - is backing the side to do just that.
"If we can finish in the top four, then we can push on and challenge for the title again next season.
"I think top four is definitely possible for us."
Those comments are likely to fill Liverpool fans with optimism after coming so close to ending their wait for a top flight crown last season.
