The 18-year-old has been carefully brought back into the fold in the first-team by Frank Lampard, and was given a call-up to the England U21s side after Gareth Southgate opted not to select the wide-man for the senior side.
When Hudson-Odoi was last in the squad, he was quickly asked to link up with the senior side due to withdrawals and picked up his first England cap.
But with limited game time this season, Southgate didn't select him and Aidy Boothroyd, manager of the U21s side, is delighted to have him but is aware he is there on a temporary basis.
"Callum has done very well. He’s only at the start of his career and had a difficult injury. We’re almost part of his rehab really, to get him back to that place where he can challenge for a senior place.
"We only had him for about half an hour last time. He was having his dinner and before he’d finished the starter we had to send him back up to Gareth.
"It was nice to spend a few more hours with him. I think we’re all right this time."
England do have another international in November which Callum Hudson-Odoi will be itching to be part of as he bids to make a claim for a spot in the side for next summer's European Championships.
Boothroyd expressed his delight at Chelsea starting to use their talented youngsters, and believes a chance is all they need to be given.
"Through what’s happened at Chelsea and seeing the emergence of these players, it might seem a surprise to some, but when you work with them, I think all that is needed is for youngsters to get an opportunity.
"For too long we’ve had players who’ve reached a ceiling in development that they can’t get through because they don’t get the chance," Boothroyd said.
"What’s happened at Chelsea is a great example of a team having to use young players and actually, they’re not bad.
"What I will say is that it’s certainly made people think differently, there’s been a shift, because people are doing so well, the top scorer in the Premier League is an Englishman- and it’s not Harry Kane, it’s Tammy Abraham, a young player, 21 years old who’s taken the chance he’s been given."
