Despite QPR's perilous position – they are 10 points off Premier League safety with just four games left to play – Redknapp has urged his players to "keep playing" and show him of what they are made.
"We've got to keep going. It’s a difficult situation but we've got to keep playing," he asserted. "I'm looking at people as well, with next year in mind, and they've all got a lot of play for.
"It's difficult now but we want to pick up as many points as we can. The last few games have knocked us out a bit and it's been disappointing but we've got to keep going.
"People think you're going to go back down and come straight back up but look at that division. It's full of quality, tradition and big clubs. It will be very difficult to come back up – that's the aim – but you're not going to do it by just dreaming."
