At the risk of simply repeating what others have said...
Obviously last night was very enjoyable, and hopefully the players (particularly Pino and Larsen, who have been harshly but fairly criticised) will feel more confident at the moment.
That said, the opposition were a huge factor. They contrived both to miss and to gift incredible chances. Better play from them in the boxes could easily have seen us 0-2 down in no time. I am sure Sage is painfully aware of that.
The biggest thing was seeing once again, and perhaps somehow more clearly than ever, the differences between how Sage plays the 343 and how Glasner played it. And, by the way, as much as I am the first to say that football is about players and not manager v manager as the media would often have it, that doesn't mean the different approaches are not important. I watched Liverpool v Forest on telly the other week and it was like watching Palace from last year. The deep, narrow block, the Forest striker being within 40 yards of his own goal when they defended. There was no doubt that this was a Glasner team.
By the same token, the most telling moments last night came when one of our players was suddenly in a totally different part of the pitch to that which Glasner would have had him in. Half way through the second half Richards was penalised for a foul. At the time he was not only in the right back position in terms of being out wide, but he was so far up the pitch that he was almost level with the edge of their box. This was in open play.
Equally, one of their big chances in the first half came when one ball through the middle put their forward away, almost 1v1 against Benitez. Where the feck is Disasi?! I thought to myself. The replay showed him to be some ten yards ahead of the other two centre backs, having chased a forward into midfield. He did it again a couple of times afterwards, though nothing came of it. Glasner would never allow that.
There were moments when the oppo played little triangles around our right side and I felt sorry for Richards as it seemed to me that Khalili had sold himself a bit cheaply, causing the problem to begin with. Upon reflection, whilst a wingback diving in matters, what is more interesting is the response. Glasner would have told Richards to leave the ball there, drop back, let others regroup, stay part of a compact unit. Sage seems to say that if the man ahead of you goes for the press, you all have to follow him.
That is how pressing works, but it relies on the forwards getting it right. If they dive in then everything else falls apart behind them, like dominos.
These are the signs of a very bold pressing game. It is very risky.
