I don't think an overhaul is necessary but the areas that that piece of shit Comolli ignored for 2.5 years will require addressing, such as a DM, a replacement for Ledley and forwards. He will also have to get a replacement for Gomes who is shockingly bad. And BAE wants to leave, so we'll need a LB possibly as Bale is seen as a LM.

So even though he doesn't have to overhaul, he will have to make changes to the squad as we are still in a relegation dogfight.

As for Redknapp? He will overhaul. I can't see him taking the Tottenham job without the promise of cash for the January window. It's the norm when there is a managerial change, there is squad change as well. There are plenty of reasons that new managers buy and sell players, partially as it gives the impression that they are doing something to change the club and move it forward. In Spurs case they do need to buy a few players at the back and in central midfield. They might need a new keeper as well if Gomes doesn't turn his form around.
