Confidence in the camp was hugely boosted by Monday night's 6-1 thrashing of Sunderland, although the Scotsman decided not to risk Clark and El Ahmadi against the Black Cats.
But Clark is progressing well after a foot injury and El Ahmadi is recovering from a groin problem, with Lambert hoping to face a welcome selection dilemma for the Carrow Road trip, where he was manager from 2009-2012.
"Ciaran hurt his foot in training the other day. Karim got a groin strain the other day, too. It was too risky to play them," Lambert told the club's official website.
"We will see how they are later in the week."
Despite the boost offered by the huge win at Villa Park earlier in the week, Lambert is keen to move on and focus his players on their next challenge.
"As far as I am concerned the Sunderland game's gone," he added.
"You move on to the next one. You can't live on that. You have to let that go and go on to the next one.
''That's what I will try to do. Now we will go and try to win a game at Norwich. The situation is better than it was a few months ago because of the way we have been playing.
"We have been in this position for most of the season and the team have handled it brilliantly.
''They haven't let their heads go down. They have kept on going and the way they are playing they don't look like a team that are down there."
