The Denmark international was close to moving to Stadio Artemi Franchi before the Serie A champions made their late move for the Arsenal striker on transfer deadline day
The 24-year old striker completed a loan move from Arsenal to the Old Lady on transfer deadline day, but according to Antonelli it could all have unfolded very differently but for a late twist of fate.

"It seemed like a dream, but, at one point, it looked as if we had him. The interest from Juventus changed the scenario, [however]."
Despite seeing the striker commit to a move to Juventus, Antonelli praised the player's professionalism, revealing that he personally called the club's president after the deal had been done.
"Having chosen Juve, he still phoned our president out of respect. He, and his agent, behaved in the right way," he added.
Bendtner spent last season on loan at Sunderland but will now head to Serie A after impressing for Denmark at Euro 2012.
Juventus had chased his Arsenal team-mate Robin van Persie earlier in the summer but saw the Dutchman complete a move to Manchester United.
