I think a great DM can transform a team, yeah. It can counteract a lot of those things, a peak Fabinho, Mascherano or maybe even Hamann would cut out a lot of the goals we've conceded and change the dynamics of games.
I'm sure Slot could have done better with what he has, I don't think anyone can claim it's been close to perfect, far from it. But there actually isn't a huge amount of options for him, if you look at our bench, it's generally lacking a lot of quality all season. Could he have adjusted tactics, he has number of times, often within games and arguably too much?
I'm not going to defend him to the hilt, and it would be no surprise if we wasnt here in a few months, I'm just not convinced we'll be any better without actually solving for our lack of quality in a few positions.
