Norwich manager Glenn Roeder accepts Leroy Lita is likely to return to Reading, while caretaker boss Phil Parkinson felt Charlton were 'asking for trouble' in their 1-0 defeat at Carrow Road.
Lita, who is on loan from the Royals, scored his seventh goal in 14 games on 60 minutes as the Canaries ensured they stayed well clear of the relegation zone.
Unfortunately for Roeder, he recognises that the forward is almost certain to head back to promotion-chasing Reading in January.
Roeder said: "It would be terrific if we could find a way of keep him but Reading know his value and I am told he will be going back there in January.
"He's out of contract in the summer and that is the one month that they could sell him.
"That's one option but the way he is playing at the moment they might want to keep him until his contract runs out.
"There's a lot of money to be gained by reaching the Premier League and it certainly wouldn't do them any harm having Leroy around.
"These days, since the Bosman years, the player is boss and at the end of the day Leroy will decide what he wants to do for the next four-and-a-half months.
"The future is in his hands so we'll just have to see what happens."
Charlton are without a win in 14 matches and in danger of being cast adrift in the bottom three.
Parkinson said: "We came in at half-time relatively pleased. We also started the second half all right but when the goal went in it really knocked us.
"We started giving the ball away too cheaply and against a good passing side like Norwich that is really asking for trouble.
"The lads are an honest bunch and kept battling away but we were looking for one good moment to unlock the Norwich defence and it just didn't come."
