So you reckon Tuchel should've been against it from the start? I'm fairly certain expectations have been set by the club and a title challenge is needed on the back of a European Cup win. Maybe Tuchel felt security adding a goal scorer into the team? Maybe Tuchel felt it would be best to have said goal scorer get used to the team from the get-go, hence the continuous starts?
Make no mistake, I prefer the front three that won us the Champions League, but I think you are well over the top criticising Tuchel's signings at the moment when it is still far too early.
