Chelsea fans can speculate about what might have happened if Thomas Tuchel had gotten his transfer wishes. If the Blues had been lining up with Robert Lewandowski, Raphinha and Frenkie de Jong in the early weeks of the season or if Dinamo Zagreb would have been beaten by a team that had a fit Pierre-Emerick Aubameyang.
Ultimately these scenarios are moot. Tuchel didn't get all of his wishes and the relationship he had developed with the new owners spiralled. Not in a malicious way but to the extent that there was a clash. Tuchel had the vision he signed up for 19 months ago and the new group wanted to remove themselves from the 'old Chelsea' and move onto pastures new.
The irony is that Tuchel, who didn't want as much involvement in transfers, then got frustrated at the lack of action in the market.
