Few things here. Farke also wants his team to have the ball, and I would say that Leeds team was better on paper than Southampton. Likewise when they went up and played the big boys, it's not like they had 60%+ in those games. They had: 43%, 41%, 44%, 38%, 45%, 42% Vs the 'Top 6', and still lost hopelessly, obviously. I don't think he went into those play off games with a 'ignore what I've been saying the last 46 games' mindset. Their two league games Vs Leeds were 43%, and 47%.
We had 59% Vs Donny in the first half and Martin would have wanted to """kill the game""" in the 2nd, that didn't happen. We were clearly more purposeful with the ball in possession and the change of shape / personnel probably contributed to that more than any Martin instruction and it helps that Doncaster are a shit bog standard L1 team.
Tldr; I don't think he's going to revert to type, because he hasn't actually changed much other than the shape - something he changed only because we were leaking goals.
