The Leeds boss says the 22-year-old has simply been 'unlucky' in recent weeks.
The £800,000 Leeds signing has fallen down the pecking order at Elland Road in recent weeks, although he was given a rare chance against Sunderland in the FA Cup last weekend.
Redfearn, however, says Sloth had simply been 'unlucky' and that he wanted to keep faith in those who had been consistently performing well for the Yorkshire side at the time.
“He’s been unlucky to be out of the team," the Leeds boss is quoted as saying by the Yorkshire Evening Post.
“We had a bit of run, a decent spell of results, and he wasn’t involved in that period. I wanted to keep faith in the lads who were, to lay a settled team down, but it wasn’t a case of shutting Casper out.
“When he gets out wide and gets himself forward, he’s someone who can cause problems and supply ball to the strikers.
“He needs his attacking head on but ability wise and attitude wise, there’s no problem. He’s got himself in there now.”
