Guernsey FC manager Tony Vance says he could struggle to get a strong side together for his club's FA Cup replay with Phoenix Sports.
The tie will be held at Lewes' Dripping Pan ground on Wednesday after the two sides
Under Football Association rules, any replay Guernsey face must be played away from home because of the cost for sides travelling to the island.
"We'll struggle, but there will be players who can come in," said Vance.
Guernsey have never played an FA Cup tie on the island before, but Lewes will travel to the winners in the first qualifying round on Saturday, 12 September.
"We've got to go and finish the job now," Vance added to BBC Radio Guernsey.
"We've made it hard for ourselves, but I have every confidence that we should have enough to get the result - but they'll have something to say about that."
