Ryan Nelsen, Clint Hill and Shaun Derry are dragging more out of their war-weary bodies than they probably expected to this season.
Redknapp said: “People say they are only Championship players but they are giving it everything and I can’t ask for any more.
“And they are good around the place. Jamie Mackie’s effort — he ain’t Gareth Bale, but does he try? He gives everything.
“They are good lads, not earning big money, but you can rely on them to come out and have a go.
“There’s no big-headedness, or big-time Charlie with them they are great guys to have around, they care for the club and want to do well.
“Ryan Nelsen, what a competitor. I took him to Spurs last year and people said I was mad? He’s one of the best centre-halfs we have had in the Premier League and one of the best characters.
“When he played, he did great for me when I needed him and he has come here and been fantastic.
“You can see why someone wants to want to take him to Toronto and make him a manager but hopefully, we will keep him for another month or six or seven weeks.”
