The Canaries are believed to be keen on bringing a new striker to Carrow Road and have highlighted Hooper, who is also believed to be attracting interest from Tottenham, as their main target.
Celtic have already rebuffed two bids from the Premier League club, both of which are thought to be in the region of £5m.
The Bhoys are reluctant to lose one of their top attacking talents, which has led to speculation that Norwich may offer a ready-made replacement to convince them to sell.
Holt, who was heavily linked with Aston Villa over the summer, has been mooted as a possible makeweight, despite his status within manager Chris Hughton’s first-team squad.
But, the club’s chief executive David McNally has ruled out the possibility of any of top players leaving before the end of the month, either via standard transfers or part-exchange deals:
“In response to (lots) of earlier messages, none of our senior players are for sale and won’t be included in any player swaps.” He wrote on his personal Twitter account.
Hooper, 24, has been heavily linked with a move away from Celtic Park this winter, with contract negotiations between himself and the club stalling.
