Agree with you Pad, no one here, or on the Arsenal board, can really be truely objective. But from my persepective I don't believe he took a dive. For that matter I don't believe Flamani did in the first leg either.
Both were impedded by a defending player, but the question is were they blocked off, with momentum bringing them down, or were they fouled. Yes there is a right and wrong answer to that question, but the ref has to make that decision very quickly based upon what he saw.
Maybe the refs got the calls right, maybe they got them wrong. Maybe one was right, but the other was wrong. Maybe we were lucky, but then again maybe we just got what we deserved. At the end of the day the answers to those questions are just opinion, and we've all got one of those.
