After seeing his side comprehensively beaten at Millwall on Saturday, Stuart Pearce is facing a battle to boost confidence ahead of the visit of the Bees.
Mark Warburton's men were themselves boosted by a late winner against Derby which knocked the Rams off the top of the table and means Brentford are level on points with Forest going into the midweek fixture.
Away from home they have won 2, drawn 1 and lost 4 of their games to date, scoring 6 and conceding 11.
