The Frenchman has stepped into James Tarkowski's shoes and impressed in the win at Preston and the draw at home to Leeds.
While last week's 3-0 loss at Brighton was a difficult day for all involved, Barbet believes playing alongside Dean will help his game.
“I played with him at the start of the season. It's very good to play with him. He's a good guy on and off the pitch. It's easy to play with him. I can't say I know him but he's helped me a lot.
“He's given me a lot of advice about his strengths and weaknesses and where he'd like me to be. I try to improve a lot as we need to be good on game-day.
“We're working on the partnership and I think we play well together.
“We have a good feeling between us. I'm very confident to play with him but as we play more games it'll improve further.
Brentford travel to Sheffield Wednesday on Saturday and Barbet knows his side face a tough task at Hillsborough as he outlined his outlined his ambitions for the rest of the season.
“Everybody knows it'll be a tough game as they're playing well,” he added.
“I've been pleased with the performances against Preston and Leeds but not so much with Brighton. “I'm happy to be in the line-up. It's difficult when you're not playing for four months. I'm happy to be in the line-up.
“I want to stay in the team, play well and help the team win. I want to score as I've not done that this season.
Barbet along with team-mate Maxime Colin were present at Cardinal Wiseman school in Greenford to pass on advice on football and French to students preparing for their GCSE exam with the Brentford Community Sports Trust.
The centre back enjoyed the experience and could understand the challenges the students have learning a foreign language.
He said: “It's funny to see people try to speak French but when they hear us speak English it's not perfect. We need to improve our English to understand everything said on the training pitch.”
Head of French Mr Ben Bird added: “The students loved it. It was amazing. It was a really good opportunity to see why learning languages is important and it can be exciting, fun and interesting.
“Bringing in the footballers has made them excited about learning French and it's not just a subject but also a lifestyle.”
