The trio are currently key to Liverpool's hopes of success now and in future.
Firmino had initially struggled to impress since joining in the summer, but has found his feet in recent weeks with a series of impressive displays.
Sturridge meanwhile has finally returned from his latest injury layoff to provide the goalscoring touch that has been sorely missing from their team once again this season.
Alongside Coutinho, the duo is looking key to the Reds hopes of success now and in future and Barnes says Firmino and Sturridge help to take the creative burden from the diminutive Brazilian.
“The burden of creativity which has been on Coutinho's shoulders for so long has been lifted,” he told the Liverpool Echo.
“We have Firmino now, who is coming good, and of course Daniel Sturridge too. So whereas before it was all up to Coutinho, now we have some help for him.”
“Liverpool don’t have lots of great individuals at the moment. I think we relied too heavily on Coutinho for creativity, but having Sturridge and Firmino in the side with him helps hugely.”
Manager Jurgen Klopp will now be hoping he can keep all three fit for the remainder of this season.
The recent 6-0 win over Aston Villa showed how good they can be when they play together, and they will keen to see that replicated as they chase down a place in Europe.
They are currently 8th in the table on 38 points, just three points behind Manchester United in 5th, meaning a place in the top six is still very much up for grabs despite a somewhat disappointing campaign.
