Ole had 1 plan ( or generously viewed 2 in total). Counterattack against sides dominating the ball , which worked, sporadically, against City, through a combination of Bruno/Pogba long-ball, playing off the shoulder/on the halfway line using split strikers, and McFred haring around. Then, for the first six months, 'go out and express yourself' (0.5) , where after Mou, the release and 'vibes' helped players elevate their games, but the comedown hit hard: or 'give it to Bruno' which, again, worked somewhat for the first 6 months. Neither of the latter two constitute a full-fledged plan though, surely.
It was clear that the coaching was barely existent - a few spontaneous patterns, flickering relationships, but no real team goals beyond the long-ball counterpunch .... a primitive version of our pre-strike moves on Sunday. There were endless reports about the low-level tactical prep otherwise: in the Europe League final we faced a palpably inferior team partly made up of Spurs rejects, but had no way of managing our lead or breaking them ground - we didn't even create many 'pre-chances' in terms of cut-out final balls.
The signings were chaotic too - we've obviously spend heavily this Summer and a more efficient recruitment team would have brought in similar profiles at half or even in some cases 1/3 of the cost (except for Eriksen/Malachia/GK), but there's a more discernible logic in terms of balance of experience and potential, a mix of craft, grit and pace, and consistent baseline top-level technical expertise.
Neither signings or recent games conclusively make the case for us securing Champions League, but all the indications in-game around building a (n adaptable, but more fluent and lateral, and gradually more possession-dominant as well as) style, as well as noises from the unofficial briefings re. training, are that Ten Hag's coaching and tactics are well above anything Ole was doing except the 'one neat trick' against high-line sides...
