The 21-year-old, who has been made available for transfer by The Hornets, has already attracted the interest of Second Division side Swindon Town after spending time on loan at The County Ground last term.
The young stopper also attracted the interest of Chairboys boss Tony Adams, with the Buckinghamshire-based club reportedly making a £75,000 bid to Watford for Ifil.
However, the young defender has snubbed Wycombe's interest in him, stating he was not keen to drop to the Third Division to play his football next season.
"I did think long and hard about the fact that Tony Adams was the manager there but, in the end, it wasn't enough," Ifil told the Bucks Free Press.
Since Wycombe's relegation to the Third Division, Adams has struggled to bring players to the club for next season.
Colchester United's Sam Stockley and Plymouth Argyle's Lee Hodges are two other players to have turned their backs on The Chairboys.
