Don't get carried away, trying to get points for style has been a vulnerability in Dutch football in the past. But if we compare the success of typical Dutch football as it has been there in the last 50 years to English football, it's obvious that the Dutch have massively overachieved and the English painfully underachieved.
Despite playing their worst match since the beginning of the season, Ajax weren't the underachievers yesterday. With spending 10 times more in transfer fees and 15 times more in wages and having to resort to defensive tactics, giving the initiative away and hoping Ajax won't suddenly start playing like they did before is not really something to boast about. It's not really a sign of strength, it something clubs like WBA do because they can't do the harder stuff. Schone might take his hat off for the way United did it, to me the cynical fouls, theatrics, and all kinds of time wasting like getting the handbags out to prevent Ajax from starting to play their game was not something to be proud of. Not if it was necessary to win and certainly not when it wasn't. It's methods like that made Mourinho successfull in the past, but I didn't expect referees to still let that happen.
