Previously he had played for Swaffham. Manager Robin Sainty said Adam was "the best creative midfielder I have ever worked with. Adam captained Swaffham at the age of 22 and was inspirational.Every sucessful team needs a midfielder who can unpick tight defences and Adam is such a player.Not only will he create a lot of goals,he will also score his fair share and I am very excited to have him in the team."
