Can't remember examples, no. A donut shape in attacking buildup play.... If Alli and Ndombele were moving that far forward/wide without instructions to do so I'd expect a reaction from the bench. Maybe there was one, I don't know.
We played it long when under pressure at the back, but also without real pressure on our defenders. With a lot of players far forward, central midfield more or less abandoned.
Really wouldn't expect both of those to happen unless that was the plan. Would have expected a reaction not only from the bench, but also from our defenders. "Where is the passing option in midfield?" kind of gestures and reactions. Can't remember seeing that.
Can guess at the intention, but it went horribly wrong and we didn't adjust when we could.
