Leyton Orient forward Alex Revell has warned Dagenham his side are gunning for revenge in the FA Cup on Saturday.
The O's head to their local rivals having already lost in the league at Victoria Road this season, and are smarting from blowing a two-goal lead to lose 3-2 at Colchester on Tuesday night.
"We need to make up for the league loss at Dagenham and we've got to make up for Tuesday as well," said striker Revell.
"There's a lot of making up to do. We have to go there and win."
