The teenage defender's contract situation is said to have alerted the likes of Newcastle, Leicester, Stoke and Norwich.
Toner, 18, has been an ever-present for Villa’s Under-21s this season after making the step up from the Under-18s and has also been captaining the team since mid-September.
The promising centre-back has even trained with the first-team on several occasions since Tim Sherwood’s appointment and has established himself as a regular in the Republic of Ireland’s Under-19 side in recent months.
However, his current deal is set to expire in the summer and, while the club are working hard on extension, the situation is said to have attracted the attention of several Premier League rivals who are keen to take advantage.
Newcastle, Leicester and Stoke are all believed to be weighing up moves, while Championship promotion pushers Norwich are also said to be among the interested parties.
Given his age, Villa would be entitled to compensation were Toner to leave at the end of the season, although fans perhaps shouldn’t panic too much at this stage over the prospect of losing one of their top graduates.
For one, the club retains a great reputation for developing up-and-coming talent and, with Tim Sherwood’s noted trust in homegrown products, there is good reason for him to remain in the West Midlands for the foreseeable future.
