Twice capped twice by Argentina, Buonanotte arrives at Stamford Bridge and will strengthen our attacking options in a campaign that will see the Blues compete across four fronts.

'I’m very happy to join Chelsea,’ said Buonanotte. 'It’s a great opportunity for me and I’m just looking to add as much to the squad as possible, help the team and help the staff.’

The 20-year-old began his career at Argentine club Rosario Central and made his senior debut in February 2022. The following January, having made 32 appearances for Rosario in which he struck four goals, Buonanotte joined Brighton.

He featured regularly for the Seagulls during his first 18 months at the club, playing 50 times across all competitions and netting five goals.

Buonanotte, who can operate as a No.10 and play out wide, spent the 2024/25 campaign on loan at Leicester City and netted six goals in his 35 outings for the Foxes.

On the international stage, Buonanotte earned his first cap for Argentina in 2023, coming on in a 2-0 win over Indonesia. His second appearance came the following year in a 3-0 victory over El Salvador.

Welcome to Chelsea, Facundo!
