The task for Todd Boehly and Thomas Tuchel was always going to be big this summer.
Following the seismic takeover from Roman Abramovich in only a couple of months and the scale of the task to rebuild a squad that had been weakened by exits, getting everything accomplished in one window always felt far-fetched.
The recent loss of Jules Kounde to Barcelona is a quick repeat of the Raphinha situation that unravelled before pre-season had got going. With both choosing the Camp Nou over Stamford Bridge, Tuchel's plans have been pushed back further.
