Redknapp took Spurs into the Champions League in 2010 and the QPR manager thinks Sherwood can achieve the same feat this year.
"That's nothing. That can be wiped out in a week, so Tottenham are still bang in there.
"They have a good squad. I think Tim will get the best out of them. I wouldn't write Tottenham off for a top-four position, they have got as good a chance as the seven teams that will be scrapping it out until the end of the season."
