In his column for The Telegraph, ex-Liverpool player turned pundit Alan Hansen says Arsenal's failure to sign a 'commanding defender and leader' means they will end up in the Europa League this season.
Hansen believes that despite Arsenal breaking the bank for German playmaker Mesut Özil, the Gunners will be weak against the kind of opposition they will face in the Champions League.
Arsenal were drawn in Group F, alongside Borussia Dortmund, Napoli and Marseille - regarded by many as being the most difficult group.
Hansen wrote: "While Arsenal have signed a great player in Mesut Özil, the harsh reality is this does nothing to solve their crucial weakness of being vulnerable when not in possession.
"Their counter-attacking approach works for them more often than not in the Premier League but the likes of Borussia Dortmund and Napoli are capable of exposing their inability to defend properly without the ball."
Despite only conceding three goals from open play in all competitions since the beginning of the season, and topping the Premier League on Sunday, Hansen believes the Gunners are due for a massive defeat:
"Arsenal have not changed. They will continue to have good runs, but then see it all fall apart with a catastrophic defeat, which is why I fear for them in this group."
Arsenal haven't failed to advance from the group stages under Arsene Wenger.
Hansen believes that Manchester United, Chelsea and Manchester City will all advance to the knockout stages.
