Chelsea have officially announced the signing of Sporting winger Geovany Quenda in a deal worth £40m.

The 19-year-old joins the club after parting ways with Sporting, where he scored nine goals and grabbed 17 assists in 86 appearances across all competitions.

Quenda arrives at the club after putting pen to paper on a eight-year deal at Stamford Bridge.

He becomes Xabi Alonso’s second signing following the £42m signing of Atalanta full-back Marco Palestra.

“It feels great to be here,” Quenda told the Chelsea website.

‘I am excited to work with my teammates and the Manager, Xabi Alonso.

“I’m a very hard-working young person and I like to help my team.

“I want to be someone known for having the right mentality to help my teammates and who does their best for the club to win trophies.”
