Nottingham Forest manager Dougie Freedman says he will work to change the "mentality" of the club.
Forest have won seven of 13 matches since Freedman took charge on 1 February but the Reds are 13 points adrift of the play-off places.
Forest surrendered a 2-0 lead to draw 2-2 at Brentford on Monday and Freedman blamed his side's "sheer naivety".
"Our mentality wasn't right and that is something I will be changing in the summer," the Scot said.
"We should have been more professional in seeing the game out,"
Seventh-placed Brentford are pushing for promotion but Forest established a two-goal lead through Tyler Walker and Todd Kane.
The home side fought back with two goals in the final 10 minutes, from Andre Gray and Spanish playmaker Jota.
Freedman said: "It's a strange feeling really because I thought we were the better side and created the better chances against a very good side.
"Overall, I am happy because we looked very comfortable. But we knew they score a lot of late goals so I was disappointed at how naive we were at the end."
