AC Milan's Pato demonstrated the importance of being aware of where a defender is positioned when attacking. His second goal against Sampdoria was brilliant. Watch the video of him receive the ball and quickly make Sampdoria's defender look foolish.
Two key lessons for players can be gleaned from this video. First, as an attacker you must be aware of where defenders are before you receive the ball. Second, as a defender don't overcommit and expose yourself.
