The 18-year-old defender made his first-team debut for the League Two side at the end of last season, which capped an impressive nine months for the youngster as he started the 2014/15 campaign as part of the club’s Under-18 squad.
Sweeney’s progress has now come to the attention of Premier League heavyweights Arsenal, whose scouts have been impressed by him in recent months.
The Gunners are renowned for their development of promising young talent and are always on the lookout for further potential to add to their ranks.
But Arsenal are not the only club keeping tabs on his progress, with Championship duo Fulham and Brighton & Hove Albion also monitoring him closely.
Sweeney, who has come through the youth ranks at Wimbledon, is currently with Republic of Ireland’s Under-18 squad after receiving his first international call-up earlier this summer.
