So what now is the club's strongest XI and bench? Lee Sobot puts together an idea of the best possible match-day 18 - with 11 days of the domestic window still left. Deals between Premier League and EFL clubs are permitted up until 5pm on Friday, October 16.
7. Mateusz Klich (CM)
Another superb purchase at around £1.5m and a permanent fixture in centre-midfield. But it's the one area where Leeds look short and might need addressing before the second window shuts. Photo by Paul Ellis - Pool/Getty Images.
8. Helder Costa (RW)
Competition is now even more fierce for a start out wide after Raphinha's arrival but Costa is generally on a sharp upward curve and a menace on the right. Switch from Wolves made permanent for around £16m. Photo by Paul Ellis - Pool/Getty Images.
9. Jack Harrison (LW)
Similarly progressive profile to Costa but on the left flank and the Manchester City loanee is set to make his move permanent for around £10m next summer. Looks worth way more than that. Photo by Shaun Botterill/Getty Images.
10. Rodrigo (ACM)
Record signing at £27m from Valencia and superb in last two outings off the bench. With Patrick Bamford excelling upfront, Rodrigo looks best starting at no 10 with Pablo Hernandez or Tyler Roberts there if not. Photo by Catherine Ivill/Getty Images.
11. Patrick Bamford (ST)
The £7m recruit has made a superb start to life back in the Premier League with three goals in four games. Perfect for Bielsa and clear first choice striker at present with Rodrigo and Roberts the next options. Photo by Oli Scarff - Pool/Getty Images.
12. Kiko Casilla
Hardly been smooth sailing since his arrival from Real Madrid but the clear alternative to Illan Meslier in goal. Absent lately with an ankle injury meaning Elia Caprile, 18, has been back-up. Photo by OLI SCARFF/POOL/AFP via Getty.
