Leading sports performance consultant Ray Wilson believes there may be personal and collective issues behind the striker's fitness problems.
Wilson, who counts Premier League stars Yannick Bolasie, Danny Rose, Nacer Chadli and Rolando Aarons among his clients, is well versed on the issue of player fitness at a top-flight level.
He is among those to have witnessed England international Sturridge struggle to steer clear of the treatment table over the course of the last year, with his 2014/15 campaign blighted by fitness problems.
The 25-year-old, a season on from being a key man for the Reds as he plundered 21 goals during a sustained title challenge, managed just 12 top-flight outings and four goals last term.
Sturridge finds himself on the rehabilitation path once again at present, with hip surgery in the United States expected to keep him out of action until October – as reported by the Independent.
Wilson was interviewed as Premier League players start returning to their clubs for pre-season training and you can read his thoughts on the science behind summer preparations on 888sport.com.
Here is what he had to say on Sturridge: “Sometimes players are unfortunate. It could be in their genetic make-up. It could be an abnormality from birth but at the same time it might not be.
“It’s hard for me to quantify because he’s had so many different issues around the same region. However, why wasn’t this done three years ago when he was breaking down before? Why is it only now? Maybe it’s because he was looking after himself then and not looking after himself now?”
Wilson has also suggested that a change in approach may be required by top British sporting institutions, bringing them into line with the philosophies adopted by their American counterparts when it comes to the handling of stricken stars.
He added: “We’re impatient in Britain. We don’t allow time for a player to get back to their best performance after injury. We want it now, now, now. With the population they have in the US if one player isn’t firing on all cylinders they have three or four alternatives.
“Unfortunately over here if Daniel Sturridge or Wayne Rooney isn’t fit we look to another 20 year old to lead us from the front. And from that comes the frustration and pressure to get them back quickly.”
Liverpool will be hoping that Sturridge returns refreshed and fully fit from his latest stint on the sidelines, with the Reds in need of his firepower and finishing ability.
They have added the likes of Danny Ings and Roberto Firmino to their ranks this summer, but proven performers at the very highest level are a priceless commodity, and Brendan Rodgers will be desperate to have key men at his disposal as he targets a return to the top four and Champions League qualification in 2015/16.
