Barnet boss Paul Fairclough has paid tribute to Oliver Kingonzila after the youngster was stabbed to death in the early hours of Saturday.
The 19-year-old midfielder, who had yet to make a first-team appearance for the Bees, was knifed following a confrontation outside a bar in south London.
He was taken to hospital but was pronounced dead in the early hours of Saturday.
Two 18-year-old youths were arrested in connection with the attack. One was released on bail. The other is still being questioned by police.
Fairclough admitted players, staff and fans alike at Underhill were shocked to learn of Kingonzila's death.
"Oliver had great potential," said Fairclough.
"The news upset me. He was a gentle giant. He was a great kid and was on his way to becoming a professional. Everyone at the club was devastated."
