"I have worked with Alan for many years. I have never come across somebody so knowledgeable and dedicated to his job. He was always prepared to answer any question or to explain in detail about injury or plan of recovery after injury. He is also a very honest and you don’t come across many people like that these days. It was a pleasure working with him." - Stiliyan Petrov, Bulgaria and Aston Villa
