Aston Villa have agreed a £10.5m deal to sign 19-year-old Brazilian winger Alysson from Gremio.

He is set to undergo a medical before joining in January, with the deal initially worth £8.7m plus a further £1.8m in performance-related add-ons.

Gremio, who finished ninth in Brazil’s Serie A this season, have also agreed a 10% sell-on clause.

Villa add Alysson – a left-footed right winger who scored two goals and provided five assists in 43 appearances this year – to an attack featuring Ollie Watkins, Morgan Rogers, Evann Guessand, Jadon Sancho, Donyell Malen and Harvey Elliott.

The Midlands club beat league leaders Arsenal on Saturday to move three points behind them in the Premier League table and up to third, behind second-placed Manchester City.

Unai Emery’s side have won their last seven matches in all competitions.
