In seven appearances this season, Sturridge has managed just one goal and, after disappointing once again at Newcastle, Souness has warned that he may have to get used to life on the sidelines.
The Sky Sports pundit having to watch as his team came away from St James Park with only a point. He was by some distance Klopp's most unsafe player and produced his goal from a nothing situation.
Jamie Carragher says he didn't see Liverpool as title contenders when the season kicked off and certainly doesn't believe it now. "I always thought Liverpool would be in a fight for the top four this season".
Former Reds defender Jamie Carragher agreed with Souness's assessment, saying Sturridge was no longer the player that terrorised defences alongside Luis Suarez at Anfield three years ago.
Klopp said recruiting a striker to go head-to-head with the likes of Tottenham's Harry Kane, Álvaro Morata, of Chelsea, and Manchester United's Romelu Lukaku had not been a priority in the transfer window.
"He had a great chance yesterday which he unfortunately fluffed but you have to combine that in the modern day game with a work ethic".
Unfortunately, for supporters of the Merseyside club, those issues will need to be solved before they can be considered a serious threat to the rest of the front-runners in the Premier League.
"I still look at Liverpool and think they didn't fix the problems in the summer that needed fixing".
"Do I think Liverpool are a genuine title challenger this season? No".
"You do think, where would Liverpool be without Philippe Coutinho right now?"
"The reason he played [against Newcastle] is because Roberto Firmino is not playing well". He scored 24 goals in 96 appearances for the Blues before eventually moving to Liverpool in 2013. In total control and they concede yet again.
"We created the chances but we have to be more clinical, that is 100 percent sure", he said.
"Liverpool don't switch quick enough between the two".
