Lambert is glad to find his players repay his faith and is confident that they will improve as the season progresses.
"I saw (Anthony) Pilkington for Stockport when I was at Wycombe," he said. "I think him and (Elliott) Bennett the way they have come out of League One football is unbelievable. Marc (Tierney) was another I knew from his Shrewsbury days.
"Ian (Culverhouse) and I knew a lot of lads who had played against us and it's like anything - when a good player hits your eye he tends to stay there and if there is a chance to give him an opportunity you look at it to bring them into an environment with better players, which might bring his game on.
"That is what has happened with a lot of lads. (Bradley) Johnson has quite rightly been talked about for the England thing but to get him for free and playing the best football he has for a long time is great.
"Foxy (David Fox) cost us £25,000 or whatever it was from Colchester at the time and he is another one."
