The striker picked up another injury in the 2-0 loss to Newcastle United.
The striker recently returned to the side after a lengthy spell on the sidelines, and impressed with two goals in the 6-1 League Cup win over Southampton.
He then featured in the 2-0 loss to Newcastle United, but picked up another injury that will rule him out for another period of time.
Given his shocking injury record in the last 18 months, many are now questioning whether the club should cut their losses on the England international, but Barnes disagrees with that way of thinking.
“You have to have some sympathy for him,” he told TalkSport.
“He’s one of our very important players and we need him. He, along with Coutinho, gives us that little bit of extra class.
“Because of his quality I don’t think it’s necessarily time to cut our losses with Sturridge. He’s obviously still a great player and we need to keep our quality players at the club.”
Given Liverpool’s current problems with strikers, it would probably be foolish for them to offload Sturridge at this stage.
So far Christian Benteke has failed to make a big impact, while youngster Divock Origi is very much still a work in progress, though undoubtedly a talent to be developed.
That leaves Sturridge as the best striker Jurgen Klopp has at his disposal, even when taking into account his injury problems.
If Liverpool were to, however, secure another forward in the near future, that situation could change dramatically for him, meaning it is currently best for both parties that they find a solution to his fitness issues.
