Sunderland manager Sam Allardyce says players' health is being put at risk by "diabolical" fixture scheduling.
The relegation-threatened Black Cats head to Arsenal in the FA Cup this weekend, with Allardyce promising to make changes to his side ahead of a crucial Premier League clash at Swansea on Wednesday.
"If the Premier League decides to put a stupid fixture midweek when they don't bloody need to, then I haven't got much choice," he said to the media..
Sunderland remain in the relegation zone despite Saturday's win over Aston Villa, with the trip to Swansea - two points and places above them - a significant one.
Allardyce has been further angered by that game being moved from Tuesday to Wednesday instead at Swansea's request, giving Sunderland a slim turnaround before a lunchtime appointment with Tottenham on Saturday.
"It's diabolical," he added. "We're flogging the lads.
"There are more and more injuries every year but it's completely ignored by the Premier League. It's unbelievable.
"If you want us to respect the FA Cup, don't put Premier League fixtures in the midweek just after new year.
"Don't give me stick when I change the side at Arsenal. Give the Premier League stick, not the managers."
