Celtic claim a fee was agreed with Manchester City for John Guidetti prior to them taking the striker on loan.
Xabi Alonso claims no Premier League offers were put to him before leaving Real Madrid for Bayern Munich.
Sky sources understand the Latics will now discuss personal terms with the 32-year-old.
The forward has been with Norwich since 2009 but manager Chris Hughton has been actively seeking reinforcements up front following Holt's return of just eight Premier League goals last season.
Holt netted 15 league goals in Norwich's first season back in the top-flight in 2011-12 and has a prolific record in the Football League, with new Latics boss Owen Coyle thought to want the Canaries captain to spearhead his strike-force.
Sky Bet Football Trader Chris Spicer said: "We had to pull the plug on Holt's market due to the sheer volume of bets we we've taken on.
"Our customers have been queuing up to back the move, which was an even-money price just two days ago and as long as 8/1 last week."
