The West Ham youth player diagnosed while away on international duty last month with Australia at the FIFA U17 World Cup in Mexico.

Dylan immediately returned to England and the club’s medical staff arranged for a further assessment by doctors.

He has already started his first course of chemotherapy at St Bartholomew's Hospital in London, which is the standard treatment for his condition. He has since returned home to rest and will continue further treatment in the coming weeks.

“Dylan is receiving the best possible care. All the doctors involved have advised Dylan that he will make a full recovery in terms of his illness and his ability to return to his football career,” said West Ham United Club doctor Sean Howlett.

“He is undergoing the standard series of treatments for his condition which is a course of chemotherapy.”

Dylan and his family are in constant contact with his teammates, coaches and support staff.

“Our hearts go out to Dylan and his family at this difficult time,” said FFA CEO Ben Buckley.

“We are heartened by the positive prognosis from the doctors and on behalf of the Australian football community we wish him a speedy recovery and return to the game.”

Qantas Socceroo Craig Moore, who was himself diagnosed with testicular cancer two and a half years ago, has been providing support to Dylan over the past few weeks.

“I spoke to Dylan not long after the diagnosis and my message was that he should stay extremely positive,” said Craig Moore.

“The success rates in treating this form of the disease are very high and I’m fortunate that I have the all clear.

“It’s tough for a teenager to deal with this, but Dylan has plenty of support from family and friends and I will be among many people who’ll be there for him throughout this time.

“I’ve told him to keep his head up and not to get too frustrated about missing his pre-season with West Ham. He’s a quality player with a great attitude and he can overcome this challenge.”

The West Ham United Academy Player of the Year is aiming to visit his teammates as soon as possible, including for the squad’s annual team photo.
