I've just seen this report that Porto manager André Villas-Boas made a few years ago when he scouted a Newcastle-Chelsea game. He was scouting Newcastle.

So much detail, thats incredible. Its ridiculous to think the amount of planning top level managers put in to devise tactics. Villas-Boas looks like he might even win the treble this season, the Europa League, the Portuguese cup and the Portuguese league, and may even go undefeated in the league as well.
