Vandals have wrecked facilities at St Agnes Football Club.
Club members found the changing room had been wrecked with chairs forced into the ceiling and windows and doors broken.
The club were astonished by the scale of the damage with flag poles thrust into walls in the portable building at Chiverton Park.
Mandy Kimmins, chairman, said: "I am absolutely devastated that anyone could have so little respect for the hard work and effort that goes into creating facilities for adults and children to play sport.
"As a club St Agnes AFC will field 13 competitive teams next season many of those youngsters who will use the changing room at our Chiverton Park venue. I cannot comprehend why anyone would cause such destruction."
The damage is estimated to be in the region of £250.
Club members will now be rallying around to help repair the damage in preparation for next season.
The attack took place at some point between midday on Wednesday and 3pm Thursday. The incident has been reported to the local police.
Anyone who would like to support St Agnes AFC in anyway or anyone with any information regarding the damage caused is asked to contact Mrs Kimmins on 07974 370666.
