#2 Kepa Arrizabalaga (Athletic Bilbao to Chelsea)
One of the big questions of the transfer window was who Chelsea would sign to replace Thibaut Courtois, who seemed certain to move to Real Madrid before that move was confirmed on deadline day. In the end that man was Kepa Arrizabalaga, a man Chelsea spent £71 million on, a club record fee, and a world record amount spent on a goalkeeper, beating the amount paid by Liverpool for Alisson just a couple of weeks previously.
Kepa has the potential to be an excellent goalkeeper, but £71 million is a massive amount of money, especially for someone so young moving to the Premier League, where we have seen so many players struggle to adapt to the physicality. We saw David de Gea struggle when he moved to England, and it could be the same for Kepa. There will also be scrutiny around his every move, especially after such a large fee. It is a lot of pressure to deal with.
