Oxford United manager Chris Wilder has criticised the decision not to allow him to make wholesale changes to his side for Tuesday's Johnstone's Paint Trophy tie with Southend United.
Oxford host Southend in the Southern Area quarter-final.
And Wilder has to keep six of the players for Tuesday's clash that appeared against Southend on Saturday.
"I don't see how picking players who play for our club is ever weakening the side," Wilder told BBC Radio Oxford.
Oxford lost to Southend at the weekend and face them again on Tuesday with Jon Franks and Tom Craddock both available.
But Wilder will be limited in the amount of changes he can make, which he finds infuriating.
"We will change it around a bit and I will receive the message from the powers that be about how many that can be, which is something I still find ridiculous," added Wilder.
"I've got injuries, I've got people who aren't fit and people who are not ready to play 90 minutes but unfortunately the rules of the competition state you are not allowed to play a weakened side.
"Whatever team I put out I would expect to play well and compete."
He added: "There will be a team from our area in the final, why can't it be us. Southend will be thinking exactly the same."
