But they didn't. We say this all the time about Arsenal to be honest, but we get criticised for not taking our chances and yet when another team doesn't take their chances against us, it's "They should've been 4-0 up". If Ramsey had scored early on against Swansea it probably would have been easier. Walcott could've scored bar Caulker clearing off the line, etc.
It's the same with one team or the other in every game. Ifs, buts and maybes. We got a point which is a perfectly good result and it took them a ridiculously good equaliser to get anything from the game, regardless of what they deserved.
You still picked up a very lucky point, and if you defend like that first half again, chances are you'll get thumped. Good as the result is, i'd still be worried about some aspects of the performance
