I doubt Glasner will ever repeat such feats elsewhere, and I doubt Palace will also repeat the achievements of the last 12 months. Just incredible.
Glasner, with less, did more than Pochettino was able to do, for perspective. No question at all.
You can sense Glasner would like to stay and that Palace would like to keep him, but leaving on the highest of highs is the way to do it.
Never go while fans are booing. Like a really good meal, prepared for you. Always leave a little bit, to show it was lovely, and just the right amount.
