The prolific striker signed today from Arsenal for £2.7million.
He had a trial with Sunderland in the summer but was turned away and eventually, he joined Falkirk on loan.
He had a brilliant time there and is currently top scorer in the Scottish Premier League.
Charlton, who have also snapped up Phil Parkinson as assisstant manager, look well prepared for promotion - should they be relegated at the end of this season.
