Chelsea will decide this week whether to pursue a deal for Pierre-Emerick Aubameyang or focus on other transfer targets, according to reports.
The Blues have been linked with the Barcelona forward in recent weeks, as Thomas Tuchel seeks to bolster his attacking options before the transfer window closes on September 1.
Chelsea have signed Raheem Sterling from Manchester City this summer, but Romelu Lukaku has been loaned back to Inter after his disappointing return to Stamford Bridge last season.
Timo Werner is on the verge of re-joining RB Leipzig and Callum Hudson-Odoi has been made available on loan, leaving Tuchel short of options at the top end of the pitch.
Aubameyang is one of the names under serious consideration by Tuchel and the Chelsea hierarchy.
The Gabon international, who worked with Tuchel during their time together at Borussia Dortmund, could be let go by Barcelona.
The Blaugrana have signed Robert Lewandowski to be their main centre-forward this season, so Aubameyang's game time could be limited.
Barcelona are set to decide whether to let the former Arsenal man leave, or whether to sanction Memphis Depay's departure instead.
Chelsea could help the La Liga giants to reach a decision were they to make it clear that they are ready and waiting to do a deal for Aubameyang.
However, the 33-year-old has long aspired to play in La Liga and may dig in his heels in a bid to stay at Barcelona after just half a season at the club.
Xavi Hernandez is said to want to keep hold of Aubameyang after he made a positive impact following his move from Arsenal in January.
But much will depend on Barcelona's financial situation as the club races to register its new signings before the La Liga season gets under way this weekend.
After beating Everton 1-0 on the opening weekend, Chelsea will host Tottenham in a crunch London derby on Sunday.
