I would actually reccomend to check Redknapp net transfedr spending as Spurs coach - he did some buying, but Levy was also selling a lot during Harry's tenure. Plus he advanced to Champions League and did well there, bringing a lot of money to the club - I guess it doesn't count, right?
I take your point about net spend, but didn't do much buying?

October 2008 to June 2012 Redknapp spent around £207 MILLION, although that figure could be reduced by up to £60 million depending on how many of the summer 2012 signings you attribute to AVB instead.
The net spend was low because Daniel Levy sold off dozens of players to cover Redknapp's spending:
£30m for Berbatov, £19m for Robbie Keane, £16.5m for Darren Bent, £10m for Crouch, £10m for Van Der Vaart, £30m for Modric; Malbranque, Zokora, Pavlyuchenko, Palacios and Kranjcar all went for between £7m and £8m too. That's around £140m for just those eleven players. Another £70m was generated from the likes of Bassong, Corluka, Pienaar, Hutton, Taarabt and Chimbonda.
Regardless of the fact the net spend was pretty controlled, Harry was using a HUGE budget. He succeeds when he has a huge budget but the only way he'd get a big budget here would be by selling Felli, Baines, Jags, Coleman and Mirallas upon his arrival. Even then, what would that generate? £75m maybe? We'd then need to buy eight players in straight away, at least five of which were ready to start 40 games each at prem level.
Harry is a big money manager only, and he demands big wages himself too. Not only can we not afford him personally, we can't afford his methods either.
