Reiss Nelson (winger) – English winger currently ripping it up in the Bundesliga with six goals in 13 games at Hoffenheim. Has played five Champions League games this season too, adding further proof to the idea that young players need leave the comfy confines of the Premier League to develop.
Joe Willock (midfielder) – Great game away in the Europa League to Vorskla as a wide right. His older brother Chris plays for Benfica, while his even older brother Matty plays for Manchester United.
Konstantinos Mavropanos – one of the first signings of new era Arsenal, Mavropanos is a highly regarded Greek centre-back. Yet to appear for the first team this season.
5. West Ham
Players aged 21 and under to play in Premier League 2018/19: four
Declan Rice (defensive midfielder) – Plays like a footballer with vast experience but is only 20 years old. Rice sits between defence and midfield, wins the ball and recycles play with his first pass.
Issa Diop (centre-back) – French centre-back with 21 appearances since signing from Toulouse. Decent on the ball, great in the air, turned 22 in January.
Grady Diangana (forward) – English wide right getting plenty of minutes for the first team. Really quick, good balance and close control but is too easily pushed off the ball at the moment. Has played 13 times this season.
