Not a possession team. Usually hard to destroy a team that is well-drilled and comfortable on the ball.
Down to both the manager(s) and players.
ETH's attacking strategy is pressing. More than player creativity, chances come from direct passing and running after winning the ball high up. Before him, it was Ole's counter-attacking. Neither one prioritises possession. Both play a 4-2-3-1, with 4 forwards.
About the players - I don't know if Fred or Bruno have ever played well in possession teams, they don't seem to have those skills. Casemiro's Real was a balanced team with some spells of possession and a lot of counters, so maybe he can work in a passing midfield (though not today's version).
Weghorst as the 10 is the symbol of the style and personnel - he's beyond hopeless on the ball, his purpose is to disrupt and press.
Maybe with Martial as the 9 doing actual hold-up play, Rashford on the left to keep TAA back, maybe even Eriksen, weak as he is, it would have been better. But fundamentally the midfield, and so the whole team, isn't set up to dominate the ball.
When the midfield strategy is to fight and scrap rather than keep the ball, and you lose the fight, this is what happens.
Possession teams can get blitzed too. It happened to LvG in his second season - 0-3 vs Arsenal and some other bad ones against smaller teams. Scorelines weren't this bad because they could hold the ball.
