Defensively we're much better than at the start of the season. Especially visible in how much better we are able to limit the dangerous counter attacking opportunities of our opponents. Those 2vs2, 3vs3 or even 4vs4 situations have become much rarer. Usually at least one of our midfielders seems to be defensively on the right side of play when we turn the ball over. I'm personally very happy that I don't have to witness the situations where all our mids are out of position and are desperately trying to run back (if they are bothered) as regularly anymore.
The intensity of ur play has also improved at least to some degree. By that I mean how we challenge for second balls, the aforementioned running back to help the defence and how we at times move the ball faster.
Don't get me wrong, there's still a lot of room for improvement, but if you can't see the clear improvements we've already made then this seems like a pointless discussion. All those improvements have led to much more consistent results in the past 3-4 months.
