I don't think signing him would help winning the titles. There is so many questions about his performance this year and I don't agree with his overrated price either. Rather have a strong striker with brain who can replace Cristiano.
I think he would help our chances of winning titles. He's no ordinary player. You know what they say...form is temporary, but class is permanent. He's still young, and he's a better team player than both our overpriced athletes. Besides, he can't do any worse than them.
His price tag might be a bit ridiculous, but hey... almost every signing Madrid make is a bit ridiculous. If we like him, and we can afford him, he's coming home. The rest will sort itself out.
