Celtic fans can enjoy six minutes of video highlights from the opening pre-season friendly, a 6-1 win over Austrian Fourth Division side Pinkafeld.
The hosts took the lead in the 28th minute with a goal that Conor Hazard would rather forget but seven minutes later Griffiths had Celtic back on level terms with a tap in from a Calvin Miller pass.
After the break the young team never let up with Mikey Johnston putting Celtic in front 30 seconds after the restart.
Henderson was next to hit the target with a dipping 25 yarder before Oko Flex showed a great touch to slot home Celtic’s fourth of the night.
In the closing minutes Jack Aitchison and Johnston were on target to give the scoreline a truer reflection of the gulf between the teams.
