No-one including Rafa is beyond criticism but please dont say his budget compares to Mancs or Chavs because it clearly doesn't once wages are included.
Of the 6 players you highlight as his mistake, we made £5.1m on sissoko (10.4 (13 Euro @ EUR/GBP 0.8) - 5.3), £1m on Bellamy (7.5 - 6.5) & lost £3.3m on Morientes (3 - 6.3) which is a net profit of £2.8m so hardly a disaster.
That leaves £7m for Crouch which we will probably get back & then spending on Kuyt & Pennant which isn't a staggering success but neither a damning failiure.
Not exactly a bad record for the 6 players you picked to criticise him with (I notice you didn't choose Torres,Masch,Agger,Skyrtel,Reina, etc).
