Chelsea are willing to include David Luiz in their offer for Arsenal striker Olivier Giroud.
The Daily Star says the swap deal is part of a web of moves that will ultimately allow Pierre-Emerick Aubameyang to complete his transfer to the Emirates.
If Giroud does complete a move to the Blues, then that will allow Michy Batshuayi to switch to Bundesliga side Borussia Dortmund.
That in turn will free up Aubameyang to finalise his move to Arsene Wenger's side.
To make matters more complicated, Dortmund are also interested in Giroud - but Batshuayi remains their first choice.
Wenger was competing with Manchester City for West Brom's Jonny Evans but it is thought both clubs have been put off by his £25million fee.
That has led the Frenchman to target Brazilian Luiz, 30, currently on his second stint at Stamford Bridge.
