You look at both Akpom and Henderson and it shows the glaring problem with the current system.
Henderson had 1 appearance for Arsenal and 2 on loan for us in 3 seasons. Then got released, went to Hull and played 1 game, farmed out on loan to Stevenage and played another 3. Released again and signed for Crawley 22 games and a relegation for them and hes now on loan at Grimsby where he's played 2 games. So at the age of 24 he's played 31 games over 6 seasons.
Akpom is younger, at 20, but has been on Arsenal's books since the age of 6. In 3 seasons of senior football he's managed 9 games for Arsenal, 4 for Brentford, 6 for us, 7 for Forest and 26 for Hull.
Compare that to Wilson, 23 and he's played 130 senior games, Thomas 97 games at age 22, Maddison 19 games at age 19, Willis 70 games at age 21.
I'm yet to be convinced the current system is doing these players any favours or helping build a potential tournament winning side for England.
