Hatters boss Graeme Jones felt his side should have done better with their chances in the 2-0 defeat to West Brom – as well as having a penalty awarded for a foul on Pelly-Ruddock Mpanzu.
Town went behind when Donervon Daniels deflected a cross past Simon Sluga, before Semi Ajayi nodded in from a Matt Phillips cross.
Jones said: “I think in football you get two things from the game, you either get reward which is points or you get development. I think we’ve added to our development away from home today from Nottingham Forest.
"If you remember we’ve gone to third place [Forest] and today second place who have now gone top, I don’t think we were fazed but it doesn’t help when you gift them a first goal at any level.
“And then it’s a second phase from a corner that Kaz does brilliantly to stay with Matty Phillips, I know how explosive Matty can be and just lets him get that ball in the box. We lose Ajayi and that is the difference in the game.
“We’ve limited them (mistakes) that’s the pleasing aspect, it’s becoming less and less. Obviously we are missing our captain today who has grown in the last two or three weeks and then you’ve got the other end of the pitch where Pelly-Ruddock just needs to side-foot the ball in first time and I’m sure it would have been 1-1.
“From where I was it felt like a penalty because Pelly stays on his feet, he loves a one-v-one duel, I’ve never seen him dive in my life and I felt like it was a penalty.
"Then Callum had a great chance, maybe it happened too quickly after he came on but you really have to take those chances at a club like this, just to turn the crowd, just to make it a bit nervy in the ground.”
