Ole gets a lot of credit for results vs. PSG and Leipzig, respectively, but there's commonalities to these kind of games. I'd argue that it isn't so much an Ole tactical masterclass as it is absolute naivety on the part of his opponents. For eg. An aggressively high line versus an Ole team that relies very much on its countering and transition from deep is asking to be beaten. Leipzig paid the price for trying to squeeze us into our own half. PSG, to a certain extent, were equally as naive, and so Ole walked out of those two games vindicated.
But Chelsea and Arsenal? They weren't so naive. Didn't play so recklessly, and rightly understood that when you get numbers behind the ball versus a team like ours it's going to give us a much more difficult game. Smaller opponents have already proved this this season. We have the individual quality to break down sides that sit back and ask us questions, but I honestly don't believe Ole has any answers to those questions. His job is largely reprieved by sporadic moments of counter-attacking success versus teams that throw caution to the wind.
