The German-born striker has ended his two-year stay at Northampton's centre of excellence for a move to London which has earned the Cobblers an initial payment of around £10,000.
Much more could follow of course and although football has seen numerous examples of the big clubs not playing fair when it comes to such transfers, Town's head of youth Trevor Gould has no complaints over the deal.
'Chelsea have been magnificent,' he said while praising the player's special ability and finishing prowess.
