Owls chief Carlos Carvalhal has questioned the Championship fixture schedulers ahead of tomorrow’s trip to Cardiff City.
Wednesday face 21st-placed Cardiff - just over 48 hours after defeating Huddersfield Town on Sunday.
In stark contrast, the Bluebirds had the weekend off and have not played since Friday’s battling home victory over Bristol City in Neil Warnock’s first match in charge.
Carvalhal told The Star: “It is very good the number of games that are played in England but the teams should play in the same conditions.
“It should be the same conditions for everybody to regenerate the team. I don’t think it is good for the competition when the conditions aren’t the same for everybody.
“Even if I was manager of a team who had more days to recover, I would still not be happy and criticise it.”
The Portuguese boss claims it is “not fair” that Cardiff have had more rest and preparation but remains confident his team can pick up a positive result in South Wales.
“I think it is not fair but this is the reality,” he said.
“We are focused on the game. Let’s not complain. We are not in the same conditions as Cardiff but we will fight for the three points. We will do our best to win the game.”
It is not yet known whether Steven Fletcher will feature. The striker was absent from Sunday’s Yorkshire derby due to “personal reasons”.
