Fabio was great. No matter who he was up against (Robben most of the time) he had that left side sewn up. Made a number of good clearances, good passes, and he's as big a threat on the set piece than anyone we have. He's so precise, he was definitely MOTM.
I'd love to see him, when not at LB, play in the midfield more. I think he can do a job to fill in for either Masch or Alonso, as he has qualities of both. He's proving to be clutch, and a great utility player who really can play different positions. If he's fit, he should have a place somewhere on the pitch. He was immense against pompey with his goal and the way he bossed the midfield. Great delivery into Torres against chelsea, and his delivery in for Yossi was perfect.
I've yet to notice a weak spot in his defending, and even though I'd like Insua to get more of a look at LB against certain sides, Aurelio is definitely a player that is a great choice to play there against stronger opposition. More than a squad player, and with a great deal of utility in many positions, he's a player I'd like to see be in the side as much as possible.
