Chelsea have agreed a deal in principle to sign Sporting winger Geovany Quenda.
The 17-year-old is expected to sign a seven-year deal at Stamford Bridge with an option for an extra season after a fee of about £40m was agreed.
Chelsea have a host of wide options on both flanks but believe Quenda, who won't join the club until 2026, is versatile enough to play on either side and will be a touchline option, capable of beating defenders in one-on-one duels.
The Portugal Under-21s international has scored two goals and has eight assists in 43 matches since breaking through into the first team at Sporting.
