Jurgen Klopp insists Daniel Sturridge's injury problems have not left permanent scars.
The striker has not scored for five games and, after Liverpool's EFL Cup defeat by Southampton in midweek, former Reds defender Jamie Carragher highlighted Sturridge's declining pace.
But, ahead of today's FA Cup fourth-round clash with Wolves, Klopp believes any physical legacy of his periods on the sidelines is not permanent.
The Reds boss said: "I thought, after the Southampton game, from the physical side it was a really good game from Daniel.A Twitter List by BelTel
"He was really involved from the first second to the last, and usually Daniel scores but he's human so he missed the chances.
"Of course, more injuries can have the effect that you lose, not the speed, but 100 per cent trust in your body when sprinting. But it's not lost forever. Daniel is the best age for a footballer so, if he stays fit, everything will be fine."
Sturridge's woes in front of goal have been symptomatic of Liverpool's fortunes since the turn of the year.
Klopp's side have won just one of their last seven matches, an FA Cup replay against Plymouth, and the Wolves tie has taken on added importance following the loss to Southampton.
As well as their cup exit, last weekend's shock home defeat by Swansea saw Liverpool slip 10 points behind Chelsea in the Premier League table, but Klopp says the problems are minor.
He said: "The difference is in the detail. What we have to do is stay concentrated, and for me it's no problem to stay optimistic because I see the progress. I'm fine with the situation. I'm looking forward to the next opportunity."
