I don't mind it. As long as a few things are taken into account:
You're better than the opposition or they don't know how to play against it. I would say the majority of results have shown this to be true in the most parts.
And as a few have said as long DR adapts in game if it is not working. DR did this at HT against Norwich, yes it probably should have been after the first goal but he did change it and is not stubborn etc. But he has adapted in other games.
How many times on here have we all said that, 'We have no style', 'What is our style of play?', 'We don't have a brand of football', etc?
We have a brand/style of football now. If, a big if, we stay up DR will have a summer transfer window to get the players capable of executing his style better.
