What is actually the advantage of paying significant fees years after the transfer? It puts you up shit creek if you fall on hard times in the interim, and it must throw a spanner in the works if the player fails and you need to move them on. They'd still be paying 30m euros, regardless of staggered payments.
I guess the advantage is that the transfer pays for itself as he helps them finish in the money-making positions, but it could still go tits up. (I don't think it will, Soldado is awesome)
@Bacon, do one.
I suppose for a secure club like Tottenham who always run a tight ship but don't have huge wads of cash to throw about in one go it makes a lot of sense.
