He played five youth players last season:
- Nathan Ake (2 starts, 3 subs)
- Andreas Christensen (2 starts, 1 sub)
- Dominic Solanke (1 sub)
- Ruben Loftus-Cheek (2 starts, 2 subs)
- Isaiah Brown (1 sub)
Hardly played and apart from first two league cup games where he played a few youth he went back to playing first team for rest of it and opted against playing more youth players against Bradford in the FA Cup which they got knocked out of.
Those five players this season:
- Nathan Ake has played over 2000' on loan at Watford
- Andreas Christensen has played over 3000' on loan at Borussia Monchengladbach and is bossing it
- Dominic Solanke has played over 1800' on loan at Vitesse
- Ruben Loftus-Cheek has played 644' at Chelsea (212' came before Mourinho was sacked)
- Isaiah Brown has played over 1500' on loan at Vitesse
