Chelsea have signed striker Pierre-Emerick Aubameyang for £12million from Barcelona, with defender Marcos Alonso expected to go the other way.
The Blues are also close to finalizing a loan deal for Juventus midfielder Denis Zakaria.
The 25-year-old Swiss international would increase Chelsea’s options in midfield.
Gabon international Aubameyang has scored 13 goals in 24 games for Barca after joining the Spanish club from Arsenal in February.
The 33 year old had a release clause of 100 million euros (£83.4m) on his contract but has only played eight minutes this season.
Aubameyang has scored 92 goals in 163 games in all competitions for Arsenal but left on a free transfer after falling out with manager Mikel Arteta.
This departure played a major role in the Gunner’s documentary All or Nothing.
Only four players have scored more Premier League goals than Aubameyang’s 68 in total since 31 January 2018 – the date of his move to Arsenal.
Aubameyang worked with Chelsea boss Thomas Tuchel at Borussia Dortmund between 2015 and 2017.
Under the German he scored 79 goals in 95 games, 38 more than under any other coach.
This summer, the Blues have signed French defender Wesley Fofana for a fee in the region of £70m, England striker Raheem Sterling from Manchester City for £50m, Senegalese defender Kalidou Koulibaly from Napoli for £34m and England midfielder Aston Villa’s Carney Chukwuemeka has signed £20m, Spanish left-back Marc Cucurella from Brighton in £60m and Italy midfielder Cesare Casadei from Inter Milan.
The deal for Aubameyang means Chelsea chairman Todd Boehly has spent nearly £250million in his first transfer window since buying the club from Roman Abramovich.
