The Norway international is a player in demand after scoring 49 goals in 49 appearances for BVB over the past 14 months.
Here, Sports Mole looks at how Chelsea could line up next season should they sign the prolific striker.
Thomas Tuchel has enjoyed a lot of success with a 3-4-3 formation of sorts since taking over from Frank Lampard in January.
That is not a formation Haaland is used to playing in at Dortmund, but he would at least remain the lone striker in this system.
Havertz's first season at Stamford Bridge has been disappointing, yet if Chelsea can get the best out of him they have one of the finest talents in world football.
Five members of the back six, including goalkeeper Edouard Mendy, effectively choose themselves when fully fit.
Ben Chilwell has not exactly been a nailed-on starter at left wing-back under Tuchel, but he is another who could possibly thrive in a new position if given some time to do so.
