Jurgen Klopp believes a fully fit Daniel Sturridge will make a huge difference to Liverpool's challenge for honours this season.
The Reds striker's future looked uncertain back in May after another injury plagued campaign which saw him drop down the pecking order.
However, the England international has impressed Klopp with both his attitude and his fitness since returning for pre-season.
Sturridge, who only started seven Premier League matches last term, has been involved in all four friendlies so far and the manager has been delighted by his contribution on the training field.

Asked if he ever had any doubts that Sturridge would stay at Liverpool this summer, Klopp told the ECHO: “What I can say is that he's here, he's training and this is 100% the best face since we got together.
“Did you see him train? He is really digging in and giving everything.
“He's reaching for the next level, a new physical level and that's really good news.
“We don't have to talk about what a difference he could make, everybody knows about it. We just need to have it. We need him fit.”
Roberto Firmino still looks likely to start the season as the first choice No 9 but with Liverpool facing a more hectic schedule following the club's return to Europe, Klopp will have to rotate his forward line.
“There will be different opportunities in different games,” added Klopp, who oversaw training at the club's Bavaria base on Wednesday afternoon.
“We need a lot of options – different players with different styles of play.
“We always need to be quick but when we can't be quick we need to be patient. All that stuff.
“I am really looking forward to it but I am happy that we still have a few weeks to train together and improve together.”
