Newcastle have been living on the edge under Jaissle — wild swings, late goals, constant momentum shifts — and that style fits perfectly for a cup tie that should open up fast. Millwall are patched together right now, missing close to ten first‑team players, and even their good moments have come with volatility: a 7-0 aggregate across two home wins, but also a 3-0 collapse to Wrexham. Newcastle’s attack has been firing even through rotation, and their matches have consistently turned into high‑event, high‑tempo battles. With Millwall’s defensive issues and Newcastle’s depth advantage, this sets up cleanly for a match where the Premier League side take control and the game pushes past the total.
