Sheffield Wednesday head coach Carlos Carvalhal has described the fixture scheduling as unfair after watching his side beat Birmingham City 3-0.
The Owls dominated the match and put on a fine display in front of a bumper Boxing Day crowd, delighting the Portuguese.
However, Carvalhal is frustrated at the fact that his side now have two days to recover before their next match against a Middlesbrough side whose scheduled game against Blackburn was postponed because of the heavy rain that hit much of the north west.
"We play Middlesbrough on Monday. Nobody recovers in two days," he said. "This is a fact I accept but we go to play a team that have not played today and they have had a week to prepare.
"This is not good for the competition in my opinion. It is not fair and it is not correct. If that team can't play for the weather then put our game one day after, and the same with Blackburn and who they play.
"Everybody must play in the same conditions and the minimum is three days."

On the game, which saw Fernando Forestieri score either side of a goal from Kieran Lee, Carvalhal said: "We waited for our moment to start opening spaces and when we did we scored one then a second.
"At half-time we corrected a few things and more importantly, I said that we need to show Birmingham that we want the third goal.
"Fernando got the third goal and after that everything was in our players' control."
