Chelsea co-owners Todd Boehly and Behdad Eghbali watched Graham Potter's side train on Thursday after spending £323m on eight new additions in January.
Enzo Fernandez, Mykhailo Mudryk, Benoit Badiiashile, Malo Gusto, Andrey Santos, David Datro Fofana, Joao Felix and Noni Madueke all pitched up at Stamford Bridge last month, while the club also confirmed that Christopher Nkunku will join in the summer for £63m from RB Leipzig.
And on Thursday, Boehly and Eghbali were pictured watching the club's new additions in action ahead of the Blues' Premier League clash with Fulham on Friday.
Several of Chelsea's winter purchases such as Madueke, Mudryk and Fofana were in training at Cobham.
However, there was no sign of Enzo Fernandez after he completed a record-breaking £107m move to the club on deadline day, raising doubts over whether he will be in the Blues' squad for tomorrow's game.
