Ahead of Tuesday's opening UEFA Champions League group match, Chelsea's head coach gave four players their first starts of the campaign in the 3-0 win over Villa: Thiago Silva (£5.4m), Callum Hudson-Odoi (£5.3m), Saul Niguez (£5.5m) and Hakim Ziyech (£7.4m).
Players such as Mason Mount (£7.5m), Cesar Azpilicueta (£6.0m) and Andreas Christensen (£5.0m) had started each of the Blues’ opening three Premier League matches, but they all dropped to the bench on Saturday.
This means that Marcos Alonso (£5.7m) and Antonio Rudiger (£5.5m) are the only outfield players who have been named in the starting XI in all four matches.
And, given Ben Chilwell (£5.7m) is still regarded as the first-choice left wing-back ahead of Alonso, investing in the Chelsea backline could prove frustrating.
Tuchel’s weekend line-up suggests managers who are planning to bring in Chelsea assets for their strong schedule from Gameweek 7 should be wary of loading up on the full three-player quota.
According to the Fixture Difficulty Ratings (FDR), each of the Blues' five matches from that point score only two.
Romelu Lukaku (£11.6m) may be the one Chelsea outfield player who managers can rely on, as his hold-up play is the focal point of their attack.
The Belgian looks an outstanding captaincy option from Gameweek 7 onwards.
But if Tuchel continues to tinker with his XI, managers may decide to limit their investment in the Blues to avoid further disappointment.
Remember, the Gameweek 5 deadline is at 18:30 BST on Friday 17 September.
