Hudson-Odoi went down in the box under the challenge from Matt Lowton and James Tarkowski and was awarded a penalty from Michael Oliver.
But the decision went to VAR and it was overturned; Hudson-Odoi was then subsequently booked for simulation.
Chelsea boss Frank Lampard though came to the defense of his player ahead of the Blues' Carabao Cup tie with Manchester United, and insisted it wasn't a dive.
"I’ve said nothing. I didn’t feel the need to. I asked him [Callum Hudson-Odoi] on the day of the game straight afterwards, after my press conference, about what happened.
"He said he got a touch. Clearly when you see it back from behind he gets a hand on his back. I know it is light. I am not saying it is a definite penalty, but it is not a dive. I am not sure if Sean maybe had watched it back on all the angles when he spoke.
"It wasn’t a dive as such because if that becomes a dive you’ll start analysing every bit of contact. How much was it? Was that enough to put Ashley Barnes on the floor or not? Was that enough for Callum to go down or not?
"That is the game. Those are the grey areas. I didn’t think the whole ‘in five or 10 years this is where the game is going to go’ was probably the right nature for what turned out to be nowhere near a clear-cut issue."
Callum Hudson-Odoi is in contention to start for Chelsea in their next game against Manchester United in the last-16 of the Carabao Cup, as Frank Lampard is expected to make several changes to his side on Wednesday.
