I made a brief comment regarding Palace earlier, with Fulham it was the opposite: It's a good thing to be ambitious, yet your team needs to justify that approach on the pitch...
They take the lead following that idiotic individual mistake, yet they are unable to build on that, even if Arsenal have become nervous. Silva will passively watch Arteta taking crazy risks -for which he was never punished...
With such a formation your midfield needs to be more solid defensively and more productive and threatening offensively -otherwise it doesn't make much sense...
When he did react tactically (with the way he did), Arsenal had gained momentum and were pushing. And in the end, he had to change again, by taking desperate gambles. The ref was obviously lacking personality which made Silva angry. But deep down I think he was angry with himself...
Fulham missed a glorious opportunity to take all three points vs Liverpool. But let's say that was their first match as a newly promoted side against an opponent with a big name. Another one was wasted tonight though. Personally I would be glad if Marco adopted a similar approach when his team plays against us...
