Ipswich Town manager Gary O'Neil has conceded that Arsenal represent one of the most difficult challenges any side can face, even when a team does everything right defensively — ahead of Tuesday's Carabao Cup third-round meeting at Portman Road.

Speaking on the club's official website, O'Neil acknowledged that Arsenal's rigid, well-drilled structure makes them straightforward enough to analyse tactically. The problem, he explained, is translating that analysis into actually stopping them.
