For where Pocchetino found them, he's done a remarkable job and is obviously beyond serious questioning (but not criticism on certain points). Yet Spurs are on course for a 60k seater, play in London, so you'll have to reevaluate their position in the hierarchy structurally soon. Maybe a few years under those new expectations, paying big wages in line with the rest, games like this will raise the heat on him but at this point, the man is practically bulletproof.
The high line did stand out when the two Juve players exploited it so well with the interchange and move but any criticism of tactical choices has to be tempered by the fact that you drop deep, play well to a shape, invite pressure on: you can still easily concede from one player moving a few steps out of his correct position under pressure, losing balance, misdirected header etc as we've seen plenty of. You can go orthodox and lose obviously so to judge his choice you have to know the odds for either path. Maybe 10 years ago the odds on succeeding with dropping deep to protect a lead would've been higher, but these days, I'm not so sure with the possession patterns being much improved across the board. It'll be interesting to see the data managers have anyway on this issue, taking into account all factors. We're going off very little.
