Third-placed Spurs have lost just once in the league since the end of August, but they passed up a chance to move within four points of the summit, and take advantage of Manchester United's home defeat against Blackburn, after conceding a late equaliser in Saturday's 1-1 draw at Swansea.
"I don't really see us doing anything. I'd be surprised. It's hard to find players, I couldn't say that we have anyone in mind we would want to bring in," said Redknapp.
"It is difficult to see me bringing anybody in really as we have a strong squad. I have Michael Dawson coming back and I have Ledley King so we are not short there.
"The young right-back Kyle Walker has done well, I have an excellent left-back in Benoit Assou-Ekotto and we have cover there with Danny Rose so I am not short anywhere. Tom Huddlestone will come back too so really we are okay, we just need to keep cracking on."
Spurs have been linked with a move for Manchester City's wantaway striker Carlos Tevez, with either a permanent or loan move reportedly on the cards, although AC Milan are favourites to sign the Argentina international. And Redknapp has reiterated that Tevez's wages all but rule Tottenham out of a deal.
"He is a fantastic player but I can't see that I could afford his wages, he is on over £200,000 a week, we don't pay that sort of money, it's way beyond what we can pay," he said.
While Redknapp was disappointed to fail to hang on to the three points at the Liberty Stadium, he remains bullish over their title hopes, particularly after seeing Manchester United and Chelsea suffer damaging home defeats.
"There is a long way to go, it just shows how difficult it is to win football matches," he said. "Who would have thought that Blackburn would win at United or Villa would win at Chelsea, no-one could have seen that.
"You aren't going to win every game and we don't have the divine right to do so. We just have to keep going."
