Imo sams original football style is still present in the game but it has morphed a lot. Reds wouldn’t wanna hear it but klopps aggression + up the pitch directly + let individual style players score is the modern equivalent.
What he’s doing with us atm is what he’s dne everywhere really, which is the old sort. Deep block, low aggression, get up the pitch through a target man / channel runs and score through crosses into the box.
It’s horrible to watch and he’s not even doing it that well, however it is effective against teams with worse individual players than us, and our results have flattered our performances.
Frankly anyone who wants him to stay another year has got their head on upside down. Particularly if they think the style is going to change one jot. More likely the results would regress to the level the performances have been, and he would be sacked by Christmas like everywhere else.
