"I am bitterly disappointed for the players because you don't always get what you deserve in this game," said Lee.
"It's always important for a manager, particularly in the position we are in at the moment, that the players show full commitment.
"I mentioned this week about things leaking out and malignant rumours, and I understand why people are unhappy if they aren't in the side.
"But what I want from players is total commitment, and that for me was the most pleasing thing. That was totally evident."
Lee, though, was far from happy with his side's defending for both goals, adding: "I was concerned the way they got through us in the later stages of the game.
"It was a bit too easy for them, and if you don't keep a clean sheet then you don't win many football matches.
"People say it was a great game, an open game but for the coaches it was probably too open.
"I wasn't happy with our defending at all. But it's not just the back four, it's the team as a whole, and that is something we will be working on in the future."
