Chelsea owner Roman Abramovich has given the club the all clear to spend big this summer.
The Russian billionaire wants to ensure the Blues are back among the elite of English and European football.
They have already signed Hakim Ziyech and Timo Werner for next season.
And more signings may be on the way, with Sky Sports suggesting Abramovich will bankroll big spending to close the gap on Manchester City and Liverpool.
Manager Frank Lampard will be financially backed, but then expected to deliver success.
Abramovich believes there is good value in the market as player prices drop due to COVID-19.
It is the ideal moment for the club to strengthen, and they are being linked with a big money move for Bayer Leverkusen's Kai Havertz, with a centre-back also on their priority list.
