The football world has paid tribute to West Ham United striker Dylan Tombides, who passed away on Friday at the age of 20 following a brave battle with cancer.

Dylan passed away on Friday morning with his family by his side having courageously fought the disease for three years after initially being diagnosed with testicular cancer in summer 2011.

A hugely popular figure among his team-mates, coaches, backroom staff, supporters and opponents alike, the Australia U22 international was loved and respected throughout the football world for his talent, determination and outstanding character and personality.

Dylan's passing has deeply touched everyone who had the honour to know him:

Dylan's brother and West Ham United midfielder Taylor Tombides: "RIP Dylan my beloved brother. You will be missed but never forgotten. You were a massive inspiration to everyone."

Joint-Chairman David Sullivan: "It's such devastating news for his family and my thoughts are with them at this time.

Joint-Chairman David Gold: "Incredibly sad to hear the news about Dylan Tombides. He was always so positive despite his illness. All my thoughts are with his family."

Manager Sam Allardyce: "Dylan was one of the bravest characters I have ever met and nobody fought his dreadful disease as hard as this lad. Football was his life and he didn't miss a day's training even when he wasn't fit enough to train because of his treatment. He had an incredible hunger for life, which was why he fought this terrible disease so strongly. All of our thoughts are with Dylan's family at this time."

Academy Director Tony Carr MBE: "It's very, very sad news. Dylan has fought this illness tirelessly and it was a tribute to him that he was able to make first-team debut despite his illness. Everyone at the Academy is devastated and words can't explain how we feel. All of our thoughts are with his parents, his brother Taylor, who is a scholar in the Academy, and the rest of his family. He will be sorely missed."

Football Federation Australia CEO David Gallop: "On behalf of the Australian Football Community, we offer our deepest condolences to Dylan's family, team mates and friends during this extremely sad time.

Fox Sports Australia Premier League correspondent Daniel Garb: "The reaction back home is absolute devastation. The Australian football community is in complete mourning. e know he will be remembered with a minute's applause at West Ham's game with Crystal Palace tomorrow but it speaks volumes of his ability and potential that games in the A-League finals this weekend - the most important matches in the Australian soccer season - will honour a player that never played a Premier League game or full international. It is with such sadness that we will never see that immense potential realised."
