Chelsea are known for big money transfers since Russian oligarch Roman Abramovich took over the club in 2003. They have spent over £1bn in transfer fees since the time and are the most successful English clubs since then, winning both domestic and continental trophies.
Chelsea re-signed their former striker Romelu Lukaku at the beginning of the season for £97m after failing in their £130m pursuit of Erling Haaland. The club spent over £200m at the beginning of last season on players like Timo Werner, Kai Havertz, Hakim Ziyech, Ben Chilwell, Thiago Silva and goalkeeper Édouard Mendy.
Former player and manager Frank Lampard was sacked when despite spending so much could not deliver success to the club, Thomas Tuchel came in and has won the UEFA Champions League and the UEFA Super Cup, he favours the 3-4-3 formation since he got to the club.
Romelu Lukaku (£97m), Timo Werner (£47m) and Kai Havertz (£72m) are the three possible front three Tuchel could start against newly promoted Brentford this weekend as the club hopes to retain top spot, the three combined costs £216m, about five times the entire Brentford squad.
