I learnt a few things, though maybe it's not all 'new'.
1) Santos is possibly the worst left back we've ever had
2) Santos asking for Van Persie's shirt pretty much showed how our team think.
3) Wenger hugging Van Persie at half time - showed he's only interested in personal achievements...ie, look at what a great manager I am at making a world class player and then selling him.
4) Vermaelen and Koscielny have both decided to turn into jelly at the same time
5) Mertesacker is a beast for us which I never expected to be fair -even though I always rated him, wasn't sure he'd cope with he prem pace, but has proved me wrong so far- best reader of the game
6) There was no point in buying a CF like Giroud if no one gives him anything to go on
7) There is no point in going back to tippy tappy football ala Fabregas - going no where fast - it's just so boring now
8) I preferred watching Swansea yesterday - thought their brand of football is 100x better than ours right now.
9) Unless something drastic happens soon - I think Wenger needs to consider his future...particularly if we fail to hold on to Walcott
10) Gazidis needs to get a new job - maybe in property - oh wait, that's what he spends his time doing anyways...sells highbury square flats.
11) I am less angry at Van Persie after yesterday - not because he didn't celebrate, but when Santos asked for his shirt - it really did show the direction of our club - and he was spot on.
