The 24-year-old has remained steadfast in his commitment ever since suffering an ACL injury shortly after Klopp’s arrival at the club in October.
But despite coming back to make his first appearance under the German in May’s 1-1 draw with West Bromwich Albion, and taking up a key role in pre-season, he is still behind on his fitness.
That is according to Klopp, who speaking to reporters at Melwood on Monday afternoon, suggested the striker may sit out for the trip to the Pirelli Stadium.
“Sometimes for players it’s harder, and it takes a bit longer,” he explained.
“Of course, he’s improved, and of course he trains good, and Danny is a wonderful guy, a wonderful player.
“But we cannot change everything every two days.
“Sometimes it needs a bit more time, even when you’re not in the best position in the squad.”
The former Burnley striker will be disappointed that his first-team return has been delayed, but with Klopp carefully managing his fitness, can hope to eventually kick on under the German.
