I really don't mind keeping Grosso, he's better than Ziegler if he's on the form he was on vs Roma..which is rare but you never know, he's experienced and can bring more to the table than Ziegler. The way he takes up the ball all the way down to the corner flag cuts into the middle to give those cut back passes can be very dangerous and its something he likes to do which can be useful when playing against tall defenders
