The Bees will host Forest at Griffin Park in the Championship this afternoon, and will be looking to pick up all three points to maintain their challenge for a top-six finish.
The London outfit will head into today’s game on the back of a 4-1 victory over Fulham at Craven Cottage, and Warburton wants the fans to rally behind the team.
“We want the same vibrant atmosphere at Griffin Park as we had at Fulham,” the 52-year-old told Brentford’s official website.
“Griffin Park can be an intimidating place when the crowd get behind the team. The team need it and appreciate it.”
Brentford are having a fantastic season and in the running for promotion to the Premier League.
The Bees are currently fifth in the Championship table with 69 points from 40 matches, just six points behind leaders Middlesbrough.
Meanwhile, Forest’s slim hopes of making the playoffs appear to have evaporated following the 2-1 defeat to Wolverhampton Wanderers at the City Ground on Friday.
Dougie Freedman’s side find themselves ninth in the league standings at the moment with 57 points from 40 games, 11 points behind sixth-placed Derby County.
