Chelsea have agreed a deal in principle to sign Timo Werner from RB Leipzig.
The Germany international striker has a €55m (£49.4m) release clause which expires on Monday June 15.
Chelsea have offered a £200,000-a-week contract to Werner, who also interested Liverpool and Manchester United.
He had publicly indicated his preference to move to Premier League leaders Liverpool but they were unwilling to pay the release clause in the current climate.
Werner had also described Liverpool manager Jurgen Klopp as the "best coach in the world".
That allowed Chelsea to move in for their number one forward target, and the 24-year-old is happy to play for Frank Lampard's side. His priority has always been to sign for a Champions League club where he can play regularly.
Werner will join Hakim Ziyech, who is joining from Ajax for £33m on July 1, as new additions at Stamford Bridge this summer following their transfer ban being lifted by FIFA in December last year.
Chelsea were unable to sign players last year and opted not to bring in any acquisitions in January, instead focusing on their main targets this summer.
The club are also interested in bringing in a new left-back, with Leicester's Ben Chilwell their number one target.
