British boxer Amir Khan has insisted that the time was right for him to part company with coach Freddie Roach.
Bolton-born Khan made the announcement on Twitter over the weekend.
Having now released an official statement, the 25-year-old has admitted that the change was necessary for the good of his career.
"After nearly four years together, in which we enjoyed some great success, I part ways with my trainer Freddie Roach. I would like to thank him for all his hardwork and help during this period and express my gratitude to him for the progress he helped bring about whilst I was under him," said Khan.
"I would also like to thank his team. I loved every minute training in LA at the Wildcard Gym, learning and sparring alongside some truly great fighters and meeting some fantastic people.
"I feel now, however, is the right time in my career to make a fresh change and bring in a new trainer. I'm looking forward, and am excited, about the prospect of working alongside someone new. I will make an announcement in due course of who this will be.
"There are some specific aspects of my game I'm looking to work on and hopefully improve. My next training camp begins in early October and I will have everything in place by then."
Recent reports have claimed that Khan's next bout could be against fellow countryman Ricky Hatton.
