"If we're going to go deep into this competition we need Shaun firing on all cylinders so if he can keep building on what he did tonight it will be great for the side."
Foran was proud of the way Johnson responded following below-par performances against both the Panthers and Dragons and felt his commitment and effort in both games had gone largely unnoticed.
The former Manly and Parramatta playmaker revealed his close mate had been down about the side's recent run of results but was determined to produce a big game to help get their campaign back on track.
"I've spent a lot of time with Shaun this year and I know that the last couple of weeks have really hurt him," he said.
"I didn't think he's been that bad. He's been really trying and his effort's been great in every game. His execution sometimes wasn't there but you can't knock the bloke's effort.
"He went out there tonight with a real intent of wanting to turn things around for this club and you could see how much it meant to him."
Foran was pleased with the Warriors improved attitude and said the players had focused all week on being more aggressive on both attack and defence.
After struggling to get a roll-on and being out-enthused around the ruck in their last two defeats, the Warriors forwards were much more physical and dominated a Broncos outfit missing six Queensland State of Origin stars.
"We just wanted to tackle hard and run hard and if you do those two things well across the park you give yourself every opportunity of winning.
"We wanted to leave blokes on the ground when we ran the footy and really create some ruck speed through the middle.
"Our middle men did a great job of that tonight and allowed the likes of Shaun and Issac (Luke) and Roger (Tuivasa-Sheck) to play off the back of it which is the style of footy we want to play.
"If we can keep building on that I'm sure we'll win a lot more games than we'll lose."
The result was the Warriors fifth win after 12 rounds and moves them back up into 11th place on the premiership ladder to sit just two points outside the top eight.
They now look ahead to Friday's clash against the Eels at Sydney's ANZ Stadium where they will look to claim their first away win of the season.
Foran was at a loss to explain why the Warriors have been unsuccessful in each of their six games away from Auckland this year but was confident they would prepare well to face his former side.
"We're so professional in our travel. It's something I've noticed coming here. (The club) get everything right.
"I'm not too sure what it is, why we haven't been able to win away from here lately, but we can start this Friday with a big game against Parramatta."
