Very true ajc, and this is really the final step for Arsenal to become a great team. The talent and mental strength is all there, and in my opinion, this is the third of three pieces of the puzzle. If they keep progressing, I would hope that by the end of the season this killer instinct would be acquired.
As for the defensive tactics, look, I understand that teams cannot come to OT or the Grove and expect to play attacking and win. But there is a huge difference between playing defensively and Blackburn's performance. Teams like Boro, Everton, and Newcastle came here and tried to take a chance that would pop up, yet defending was on their mind. However, Blackburn was simply anti-football on Saturday. There were opportunities to break out and test the keeper, but they just hoofed the ball away. They played with no balls, and simply hacked away at some Arsenal players. How Aliadiere didn't get a penalty I will never know. Yet Blackburn are really hurting themselves as far as funds go, because these defensive tactics are deterring fans, thus eliminating ticket revenues, but that's their own issue. But in general, Blackburn's tactics are no excuse, and like I said, Arsenal need to build a killer instinct, and that will come over time. At least the other leg will be a bit more open.
Also, Ratherton, Arsenal don't really make the massive signings like Man U and Chelsea, so I think it's a bit unfair to classify them like those squads. I mean, look at Everton. AJ cost 8 million quid. Rosicky has cost 7, as has Walcott at the time, while Eboue, Toure, Fabregas, Clichy, Senderos, Djourou, Flamini, and van Persie all were bought for chump-change. Hell, we even were paid in escence to take Gallas, as Cole was an acadamy player and as part of the deal, Arsenal picked up 5 million. In fact, over the past 5-10 years, only Hleb, Henry, Reyes, and Wiltord have at least 10 million, and none of these have broken 12 million or so (Reyes had a deal starting at 10 going to 17 relying on caps and goals, and obviously he didn't pick up too many of either of them). I don't mean to spark a fight or anything, just pointing it out;)
God damn brewery!!!
