Don't buy that at all. If he's so interested in money, why turn down the move to Chelsea and hold out for a move to Spurs? Did you not read the Danny Rose interview a couple weeks back?
To be honest nobody knows the future, but the shorter the contract, the lesser the fee, the more wages go to the player, signing on fee etc. Ross could end all this greed speculation by signing a short term deal, 6 months / 1 year with a guaranteed 30m / 35m buyout clause. As someone said even Suarez done that.
