Trouble with this line of thinking is this: 1. We probably wouldn't get £40M, but for the sake of argument let's say we manage to get £30M, which is at the top end of what we're likely to receive IMO. 2. Of that £30M you have to take off agent fees,paying off contracts etc. 3. When you're buying these new £10M players again, you have to factor in agent fees, signing bonuses. 4. Wages - Mascherano isn't on a huge wage - and the wage bill of 4 £10M is going to be vastly higher. Summary: The money won't go that far - it certainly wouldn't let us purchase four £10M players.
