Sanchez - out of the blue, 18 games and into the Spain national team.
Alzate - From Orient to 31 appearances and 4 for Colombia
White - ever present, hot property
Mac Allister - Eased into the Premier League and now one of our top players, 22 years old.
Moder & Zeqiri - watch this space
Not including Lamptey because he was quality before he got here.
Connolly probably is, and will never be, good enough...
Potter's done a phenomenal job in bringing those four players through - they're probably worth more than £100m all together.
He's also done a great job with Biss, who has come leaps and bounds under Potter, especially this season.
He's OK with some pf the older ones too - Veltman was supposedly a laughing stock in the Dutch league and amongst Ajax fans.
