Following a positive start to his career in west London, Forrester is confident he made the right decision.
He told the London Evening Standard: "I trained with Frank de Boer and Dennis Bergkamp a couple of times and they both gave me some good advice. They used to mess around before training and would take free-kicks and put them in the stanchion in-front of everyone! I am an Arsenal fan so that was great. Speaking and training with people like that gave me a lot of confidence."
