You have said it all. Yesterday was the first time that I have seen Arsenal fight and win an important match with all determination. Look at how Arsenal played Madrid as if they're a mediocre team and they couldn't do anything but to accept the shame and disgrace.
I don't see any hope for Madrid in the second leg because it's like a mission impossible for them since Arsenal wouldn't just sit down fold their arms and watch Madrid win them by scoring four goals without retaliating back. I can't wait to see Arsenal in the semifinals.
That is the beauty of the game, no matter how much one wishes to determine the future outcome you just can’t but I am trusting Arsenal to replicate same performance in Spain and send Madrid out of the champions league. It will still seem unlikely to some but it might happen.
