Chelsea have announced the signing of forward Nicolas Jackson from Villarreal.
The 22-year-old joins the club on an eight-year deal after scoring 12 goals for the LaLiga side last season.
He began his career at Senegal Premier League side Casa Sports before moving to Villarreal in September 2019.
A successful season with the Spanish side saw him make 38 appearances in all competitions for the club and he was called up to represent Senegal at the World Cup.
Co-sporting directors Laurence Stewart and Paul Winstanley told the Chelsea website: "We are excited to welcome Nicolas to Chelsea. He is a young player with big potential, as he showcased for Villarreal last season.
"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 teammates."
Jackson's arrival came shortly after the Blues confirmed that Ruben Loftus-Cheek had completed a permanent move to AC Milan.
The 27-year-old joins Milan on a four-year deal running until June 2027.
His departure from Chelsea comes after 19 years with the club, having joined their academy in 2004.
He made 155 appearances for the Blues, scoring 13 times, and earned Premier League, Europa League and UEFA Super Cup winners’ medals during his time there.
An impressive loan spell with Crystal Palace also saw Loftus-Cheek selected for the England squad who reached the semi-finals of the 2018 World Cup in Russia.
However, he struggled for game time under successive managers during the second half of last season.
His move comes as part of several recent outgoings from Stamford Bridge, with N’Golo Kante and Kalidou Koulibaly among those joining sides in Saudi Arabia’s Professional League.
Earlier this week, goalkeeper Edouard Mendy joined Saudi side Al-Ahli, while Arsenal completed the signing of midfielder Kai Havertz.
Mason Mount is also set to depart after Manchester United agreed to sign the England midfielder for an initial £55million.
United are set to continue contract discussions with David de Gea as his current deal runs out.
With lengthy talks having yet to produce a resolution, the veteran Spaniard, 32, will become a free agent on 1 July.
It had been reported De Gea signed a new contract extension, only for the club to withdraw the offer and come back with different terms.
The Red Devils have been linked with a move for Inter Milan goalkeeper Andre Onana, but confirmed on Friday evening talks with De Gea remained ongoing.
They also confirmed that midfielder Marcel Sabitzer and striker Wout Weghorst would return to Bayern Munich and Burnley respectively following the conclusion of their loan moves.
Manchester City assistant manager Rodolfo Borrell has left the treble winners to become sporting director at Major League Soccer side Austin FC.
The Spaniard joined City from Liverpool in 2014 as global technical director, before being appointed head of coaching for the academy and then joining Pep Guardiola’s backroom team.
Borrell was named assistant manager ahead of last season, which saw City win the Champions League, Premier League and FA Cup, but becomes the second of Guardiola’s lieutenants to leave this summer following Enzo Maresca’s appointment as Leicester boss earlier this month
