Brewster scored 1 goal in every 2 games for Swansea in the Championship and both he + Solanke were prolific at youth level for England prior to those moves.
You can see how clubs could get lured into paying big money for those two.
Who would pay £5M+ for Connoly at the moment?
Fair point - but Brewster only scored 3 this season for Sheff Utd so just shows how unpredictable it is for all young strikers in the EFL / PL
