Redknapp takes his Rangers side to West Brom in an FA Cup third-round replay on the back of Saturday's hard-fought goalless draw against his former employers Tottenham.
Despite QPR's lowly status, performances and results have slowly started to improve since Redknapp replaced Mark Hughes as manager at Loftus Road and the 65-year-old has praised the likes of Shaun Derry, Clint Hill and Jamie Mackie for their commitment to the cause.
"They love the club and want to do well," he said.
"They're lads that people write off, saying they're only Championship players, but they're giving everything and I can't ask any more than that.
"Mackie isn't Gareth Bale but he gives everything and I couldn't ask for any more from him. They were great against Spurs."
Redknapp has also been impressed by the unselfishness of his more senior professionals.
"They're good lads, not earning big money but they give everything," he said. "If you ask them to sit on the bench they do it.
"There's no `Big Time Charlie' about them, they're great blokes to have in the dressing room."
