I think Ronaldinho's pass was harder to pull off.
How obvious was Kaka's pass? It didn't require god like vision and speed of thought, make no mistake about that. Crespo's run was alright, nothing out of the ordinary. Those runs would typically be met with a high ball over the top. Kaka decided to play it on the deck and it was perfectly executed. Defence-splitting.
Ronaldinho's pass requires more vision than Kaka's. At the exact moment Guily makes his move, as soon as he jinks and I mean the EXACT second, Ronaldinho acts.
It's as top level as you can get. Ronaldinho's mind is made up as soon as Guily starts to lean forwards to begin his run.
It was quick-thinking, it was bright and it was something done which has stuck with me from the moment he did it. Breathtaking stuff.
Another thing that makes it so special is that he's flat footed and Guily is at a 90 degree angle.
I'm not too worried about the runs and finishes, but Ronaldinho's pass makes Barcelona's goal more delightful for me.
