Brighton knew what they do. They signed a true gem of Olympiacos. As far as i know he's strong physically, he can also play in various position such as striker or behind the striker. Paying him for 12.5 million looks so bargain consider they can sell him multiple times more once they develop him well.
I see it as a smart move by Brighto. Not so many knew that kid, but he has very big potential. Worthy to try.

They're preparing to back home with bags of money in the future.
