The event, at Cleves School in Walton-on-Thames, was organised by Rob’s former colleagues at Surrey Football Coaching after Rob died age 21 in November 2014 of testicular cancer.
It is the second football event held in Rob’s memory, following an event organised by fellow students at Portsmouth University.
Rob’s parents and brother were there to help on the day.
They will divide the money raised between CLIC Sargent, after Rob received support at Southampton Hospital, and funding the supply of DVDs made for secondary schools and universities to raise awareness of testicular cancer.
Rob's parents said: “Our amazing son Rob inspired so many of the children and friends he met.
"The football festival was a wonderful celebration of his life. The children released 21 balloons at the end of the event and everyone enjoyed the day.
"With the money raised we can help so many others to fight cancer."
CLIC Sargent Fundraising Manager Helen Farquharson said: “Rob clearly made a great impression on all who knew him.
"It was a privilege to be part of this event and we’d like to thank Surrey Football Coaching and Rob’s family for helping CLIC Sargent to get closer to its aim of being able to support three out of three children and young people with cancer.”
