Chelsea have completed the signing of Pierre-Emerick Aubameyang from Barcelona, seeing the forward reunite with his former Borussia Dortmund coach Thomas Tuchel at Stamford Bridge.
Tuchel's side have been in the market for attacking reinforcements since allowing Romelu Lukaku and Timo Werner to return to their respective former clubs, Inter and RB Leipzig, after disappointing spells in west London.
Aubameyang enjoyed a successful half-season in LaLiga after leaving Arsenal in January, scoring 11 goals in 17 league appearances for Barca last term – a tally only bettered by Memphis Depay (12 goals in 28 games).
That form has persuaded Chelsea to agree a deal worth £10.3million (€12m) for the striker, who has signed a two-year contract with the Blues.
It is expected that Marcos Alonso will head in the other direction, though seemingly as a separate deal.
After the signing was announced, Aubameyang told the club's website: "I'm really happy. It's an honour to be part of this team and I can't wait to start. I have some unfinished business with the Premier League so it's good to be back and really exciting."
Aubameyang will hope a reunion with Tuchel allows him to rediscover the goalscoring form that convinced Arsenal to part with a then-club record fee for his services back in 2018.
The Gabon international has scored more league goals (56) and recorded more goal contributions (63) under Tuchel than any other coach in his career to date.
Aubameyang racked up those figures in just 63 games under Tuchel at Dortmund, averaging a goal every 94 minutes in league action during the German's spell as Dortmund boss – also a career-high figure.
Earlier this month, Tuchel insisted he had no concerns about Aubameyang's attitude despite his difficulties at Arsenal.
"We had a very close relationship. Always when we played him here with Arsenal, there was always straight away this close bond," Tuchel said. "They stay your players, in a way, and Auba is one of these guys."
The 33-year-old could make his Chelsea debut against Leicester City on Saturday, with the Blues eyeing a response after suffering a chastening 3-0 loss at Leeds United last time out.
