18-year-old Ampadu, who has already won six caps for Wales, has only featured five times for the Blues this season.
"He's played the odd Europa [League] game or cup game for Chelsea and, because of that talent, I can see Sarri wants him around the first team," said Giggs.
"But it's just been a bit stop-start, together with the injuries, which is frustrating because he is an amazing talent and he's shown that in the games he's played.
"We've had players in the same situation - David Brooks, Harry Wilson, Ben Woodburn - talented players who've gone out on loan and benefited from it. But if he can force himself into that Chelsea squad then that would be great."
