Chelsea could reportedly make another three signings before the end of this summer's transfer window.
The Blues have already spent heavily on Hakim Ziyech, Timo Werner and Ben Chilwell ahead of the 2020-21 campaign, while central defenders Thiago Silva and Malang Sarr have both joined on free transfers.
However, according to The Sun, Frank Lampard's side are still targeting three more signings in the coming weeks as the Blues look to become challengers for the biggest prizes once again.
The report claims that Bayer Leverkusen's Kai Havertz and West Ham United's Declan Rice remain leading targets for the London giants in this summer's market.
Meanwhile, Chelsea are said to be determined to sign a new goalkeeper due to Kepa Arrizabalaga's struggles between the sticks since arriving in a world-record move from Athletic Bilbao.
Lille's Mike Maignan has been linked with a move to Stamford Bridge, but a recent report claimed that Rennes stopper Edouard Mendy had emerged as a leading target.
Chelsea are due to open their 2020-21 Premier League season away to Brighton & Hove Albion on September 14 and drew 1-1 with the same opponents in a friendly at the Amex Stadium on Saturday afternoon.
