He operated centrally as England Under-21s drew in Slovenia on Friday night, with manager Aidy Boothroyd keen to experiment.
Hudson-Odoi's peers have remarked that the 18-year-old appears to have evolved physically during his five months out.
"Players can get quite down about serious injuries but he's come back stronger," Boothroyd said.
"He's certainly lost none of his explosive power, which can be a worry with an Achilles. He has to make sure he looks after himself. Doing that stuff off the pitch allows them to flourish.
"I can't say anything but positive things about him. He's got a brilliant approach to life.
"His attitude has been first class. His enthusiasm has been infectious. It gets everybody going, they raise their levels. Hopefully we can't hold on to him and he gets in the first team."
