I think what's quite interesting is that we've been notoriously bad starters of games. Last season we often found ourselves a goal down early and then we had the best second half record out of everyone. In this '18 wins from 21' form, we usually don't look in the game in the first half.
But now that seems to be a tactic. It's like we accept we're going to be shit and so just work hard on defending by purposely staying on the back-foot in the first half and not trying anything risky. And then we trust our fitness levels to take the opposition on running power alone in the second half. Looking at the goals we're scoring recently, it's not like we're doing anything special from a technique POV. It's just athlete ball and the opposition getting physically tired.
In the bigger games - and by that I mean the CL - our inability to keep 65% possession might get us into trouble. But it's hard to see it being too much of a problem in the league.
