Arsenal, Tottenham and Southampton are currently the top developers of young players in the Premier League.

The north London rivals and Saints each have nine players in their squads who have stepped up from their youth ranks to play in the Premier League, according to a new Sky Sports study.

However, no current Bournemouth or Swansea player has progressed from the youth ranks to play for their club in the Premier League, while, of their current squad, Kelechi Iheanacho is the only former Manchester City youngster to play for the current first-team squad in the top flight.

METHOD

With transfers of young players meaning many footballers spend different phases of their development at different clubs, gauging how many players a club has developed is a complex matter. So for this study we established three key rules. Players are only considered if…

- They joined their club before their 18th birthday

- They played for their club's U18 side or equivalent

- They had not played a senior match for another professional team before joining their current club

THE STANDINGS

YOUR CLUB'S YOUTH PLAYERS

ARSENAL - 9 players

James Ward-Prowse is one of nine youth graduates in the Southampton squad to have played in the Premier League

Gareth Bale, Theo Walcott, Alex Oxlade-Chamberlain… the Southampton academy has produced a raft of top talent in the past and continues to do so today, with nine of Saints' current squad featuring in the Premier League after stepping up from youth level. James Ward-Prowse and Matt Targett are among that number, while the likes of Sam Gallagher - who joined Saints as a 17-year-old from Plymouth - suggest the future's bright on the south coast. Other Saints youth players to get a taste of Premier League action are: Harrison Reed, Ryan Seager, Jake Hesketh, Dominic Gape, Jason McCarthy, Lloyd Isgrove.

MANCHESTER UNITED - 8 players

James Wilson scored twice on his first Premier League appearance

Famed for the crop of players they brought through in the 1990s, Manchester United continue to produce plenty of homegrown talent, with eight of the current squad being former youth players who have enjoyed Premier League game-time. Cameron Borthwick-Jackson is the latest name on the list, while James Wilson and Paddy McNair are included in that figure, too. So is Adnan Januzaj, who is out on loan at Borussia Dortmund. The Brussels-born Belgium international joined United from Anderlecht as a 16-year-old. Jesse Lingard, Andreas Pereira, Will Keane and Tyler Blackett have also stepped up to the first team.

The other youth graduates with Premier League experience are Luke Garbutt and Conor McAleny.

WEST HAM - 6 players

Reece Oxford made his Premier League debut aged 16
