Former rivals Paul Scholes and Emmanuel Petit were united in condemning Arsenal's woeful first leg display after the task proved too tough for them to overcome against Monaco in the return match.
The pair were pundits for ITV, and both said Arsenal only had themselves to blame after yet another last 16 exit.
Arsenal won 2-0 on the night away at Monaco, but the 3-1 loss meant they exited on away goals. The duo were in agreement that it was the attitude of the players in the first leg which was their downfall.
Ex-Manchester United star Paul Scholes said: "Arsenal will probably get all the plaudits tonight, a good 2-0 win, but really Arsenal are a much better team than Monaco, they should be knocking this team out the tournament without a shadow of a doubt. The complacency of the first leg has really cost them."
Defender Per Mertesacker gracefully told ITV after the game, as reported by The Star, that Monaco were the best team and deserved to go through to the Champions League quarter-finals.
Former double winning star Emmanuel Petit did not feel this was the case. He said: "This is where I disagree with Mertesacker, I think the best team didn't go through.
"They should have big regret. They are out because they lost 3-1, but the way they prepared they knew they were superior, technically as a team, individually as well. They were too arrogant, this is why they lost qualification."
In previous years Arsenal have been knocked out at the same stage by AC Milan, Bayern Munich and Barcelona, but this Monaco side do not have the same reputation. What the result proved is once again that even in the knockout phases of the Champions League, upsets can happen, and that at least should be welcomed, although the Gunners will wish they could have pulled off similar surprises in previous years against the Spanish or German giants.
