The European champions Chelsea, however, has emerged as the most serious club for the £150m-rated Bundesliga player, with Thomas Tuchel knowing fully well that Haaland is the man to resolve the standing issues at the top of the pitch.
The deal will not be easy to achieve, but here, we look at the scoring issues which have prompted Chelsea's interest and examine the ways in which Haaland could take them to another level.
Chelsea's finishing problem predates Tuchel's appointment. It was apparent throughout Frank Lampard's tenure and it was issue for Maurizio Sarri and even Antonio Conte before him.
Eden Hazard was productive and Tammy Abraham has impressed in patches but the club have not had a truly elite presence in the central striking role since Diego Costa's departure in 2017.
Timo Werner may yet prove himself in that regard. He certainly has the pedigree having scored 95 times in 159 appearances for his previous club RB Leipzig.
Erling Haaland made a total of 28 appearances last season scoring 27goals in 28 games, while Timo Werner made a total of 35 appearances and scoring only 6, Haaland could be the key to Chelsea’s issues.
