"It's been a good week and we are on a good run," Redknapp said after the 1-0 win against Spurs.
"We're playing well at the moment and over the last five or six weeks we've really started to lift off.
"I thought five weeks ago we had no chance of staying up and I used to go home thinking 'How am I going to keep this team up?'
"But then the transfer window came and we brought in some players that made a massive difference to us.
"I feel the lads that were already here feel the difference and we are a totally different team to what we were."
