so let me rephrase this, Aquilani last year signed for Liverpool for 25 million, right? which I'm sure wasn't paid on the spot
now we loan him for a year with possibly a clause to buy him
we essentially would buy off the remainder of the transfer fee Liverpool was set to pay, let's say 17 million
now if we buy Martinez and paid 5 million and next year we sell him the other team will at least pay 7 million, any more would be a profit
