"It was just what we needed in terms of performance. We should have scored more but I can't complain because we scored in the first half. We've got nervous before when we've had a measure of possession but not scored," Lampard said.
"We were so positive from minute one. It's a big win and one we must pick up on and replicate. It's a nice example of the standard we have set.
"It feels nice to smile in a game and enjoy what you are watching."
For Callum to score in the six-yard box is more exciting than him scoring from 30 yards without a doubt," said Lampard of Hudson-Odoi, who signed a five-year contract in July.
"It means he is willing to get in there. It wasn't the only time he did that. His overall performance was a statement of what he has to do.
"That was the real Callum. If he carries on like that we will have a real player."
