The Italian manager said Hudson-Odoi played well but was aided by the fact PAOK were reduced to ten men after just seven minutes.
"I think, as you know, I want to play a centre midfielder with a very technical player, so for me the centre midfielder is Jorginho or [Cesc] Fabregas", he told a news conference.
Khacheridi was forced to hack down the former Arsenal striker and was shown a red card by Kristo Tohver inside the opening seven minutes, making a tough task for PAOK all the more hard.
"Obviously, if I want to come back, I need to be efficient and show the manager I am ready", said Giroud before the game. "Not easy to put him in the starting XI because, maybe, on the bench in the Premier League matches there was Moses or Pedro, so it's hard not to put that kind of player in the starting XI".
Hudson-Odoi only has 36 minutes of football to his name with two appearances in the Europa League.
"And in the long period, to become the best team in Europe".

Speaking to BT Sport about his memorable evening, Hudson-Odoi said: "I couldn't believe I got the opportunity to start". Every time I got the ball I wanted to do my stuff.
"I want to see we learned our lessons".
"So I think that if there were two different players, it would have been the same". Loftus-Cheek also provided more evidence that he is progressing tactically under Sarri's guidance, and numerous starters got some rest ahead of Fulham.
"You'll always remember me, huh?".
Giroud added: "The main target was to win, we needed a strong team reaction and we did it well tonight".
"It was really very good, especially because, before the match, we knew very well that we were first in our group after the result of BATE Borisov". Looked a little too eager to impress early on, understandably, but soon calmed down and scored an impressive goal before clipping in an inviting cross for Morata to get in on the fun.
'I had a good assist from my team-mates, I love this kind of ball behind the defence. The French striker has five goals in his last four Chelsea starts-and four goals in four European starts.
