No, not at all.
It would be perfectly possible for me to buy 50% from Rio Ave for a completely different price, there is no connection other than we need to own 100% before we register him.
This is exactly what happened with the mangala deal. We paid £24m for 60%, and when that was discovered lazy journalists did the maths and worked out it came to £42m for 100%.
What actually happened is that we negotiated the sale of different pieces from different parties for differing amounts, totalling £32m.
If Rio Ave wanted to they could sell 50% to us for £1, that doesn't mean Benfica have to sell their half for £1.
