Chelsea has finalized the signing of Portuguese midfielder Dario Essugo from Sporting CP. The 20-year-old joins the newly crowned UEFA Conference League winners for a fee of 18 million pounds (24.3 million U.S. dollars) and has signed a contract through June 2033.

Essugo, known for his tough tackling, spent last season on loan at La Liga side Las Palmas, where he made 27 appearances and was a bright spot in an otherwise difficult campaign that ended in relegation.

The Portugal under-21 international made history as the youngest ever player to debut for Sporting's first team, breaking the record previously held by Luis Figo when he took the field at 16 years and six days old. He also spent the 2023-24 season on loan with Chaves, appearing in 14 matches.

The deal was initially agreed upon in March but was completed with the reopening of the transfer window ahead of the FIFA Club World Cup. Essugo will join Chelsea's squad for the tournament, which kicks off with a match against Los Angeles Galaxy on June 16.
