It depends on your definition of a 'defensive team' really. You have teams that pull everyone back into their own half and park the bus in front of the goal, much like what smaller teams do against big sides when playing away. I'd be the first to admit that we did this under Gerard Houllier who was ultra defensive. Under Rafa however, whilst we may play deep, we push players forward when attacking. We look like a 4-5-1 on paper but when we attack, it becomes a 4-3-3, with Torres at the fulcrum of the attack and both Kuyt and Babel on either side of him. Stevie then moves up to play behind Torres. Man Utd have scored 72 goals this season thus far, Arsenal 64 and both Liverpool and Chelsea are on 60, not too far behind.

On the subject of Agger vs. Vidic, I personally think Skrtel is more similar to the Serb.
