Alfreton Town manager Nicky Law says his side must look to recreate their FA Cup form when they return to Blue Square Bet Premier action.
The Reds hit the woodwork four times in a thrilling 4-2 loss to Leyton Orient in their second-round tie on Sunday.
Law said: "We have gone toe to toe with a League One side and with a bit of better decision making and a bit more luck we could have won.
"Hopefully the lads can revisit that performance in the league."
He added: "It was crucial we came out with credit and I think we did that. We did ourselves proud and can hold our heads up high."
Alfreton, who lie in 14th place in the table, face high-flying Wrexham on Tuesday.
