According to reports, Chelsea will pay a substantial fee of over €40 million to secure Hato's transfer. The deal also includes a clause that benefits both parties in the future.

Hato, who is 19 years old, will sign a seven-year contract with Chelsea, keeping him at the club until 2032. This long-term deal suggests that Chelsea sees great potential in the young player.

It's worth noting that Hato can play in both left-back and centre-back positions, making him a versatile addition to the team. He is expected to learn from and support Marc Cucurella, who currently holds the left-back position.
