Granulocytes, specifically neutrophils, help the body fight bacterial infections. The number of granulocytes in the body usually increases when there is a serious infection. People with a lower number of granulocytes are more likely to develop bad infections more often.
Congrats on a sick trade. If the buyout happens before the options expiration, you can exercise your options for stock, purchase the stock at $28.00, and sell the shares for $40.00 and make $12.00 per share (less the price of the options). Realistically, the value of the call option will go up to $12.00+ and you can just sell the option.
A buyout clause, simply put, is the valuation that a club has of a player. If an offer equal to the buyout clause is met by a purchasing club, the selling club must accept the offer and the player may move. The key difference here is that under Spanish law, it is not the purchasing club that makes the payment, but the player himself.
