The Blues spent nearly €250 million (R4.6 billion) ahead of the current campaign, but Frank Lampard struggled to get all his new stars firing, which ultimately cost him his job.
Tuchel took over this week, with one of his main tasks being to get Timo Werner and Kai Havertz in and amongst the goals.
However, the former Borussia Dortmund and Paris Saint-Germain boss reportedly also wants to bring some more new faces to Stamford Bridge over the next two windows.
According to the Daily Mail, Erling Haaland is the German tactician's main target, with Dortmund potentially being forced into sales after being hit hard by the financial impact of the coronavirus pandemic.
Haaland has been in sensational form since joining the Bundesliga side, scoring 37 goals in 37 appearances for the club.
