Chelsea have completed the signing of Villarreal attacker Nicolas Jackson.
The Senegal international has signed an eight-year contract in a 30m move from Spain.
Jackson was part of his country's World Cup campaign last year.
The 22-year-old scored 13 goals in 38 appearances for the La Liga side last season, including nine in the final eight league games.
He is a young player with big potential," said co-sporting directors Laurence Stewart and Paul Winstanley.
"We believe he is ready for this next step in his career and look forward to him working with our new head coach, Mauricio Pochettino, and his Chelsea team-mates."
